At first glance, the answer seems obvious.

Asked the secret to her now nearly 10-year marriage to John Legend, Chrissy Teigen told Vogue in 2017, "Taking super sexy photos like this. Then the Sports Illustrated Swimsuit cover model promptly popped a set of false monster fangs in her mouth and snapped a grimacing selfie.

It's that willingness to poke fun at themselves (and each other) that's made Teigen and Legend such a rock solid couple. And the reason why when Teigen joked at the start of quarantine in 2020 that she and the 12-time Grammy winner were "def breaking up after we can leave the house," the overwhelming response was, as one fan put it, "OH THE HELL THEY ARE."

Because, duh, not even close.

Having weathered a series of storms—including the loss of son Jack in 2020, Teigen's decision to get sober after what she called "point blank, just drinking too much," and the backlash that came after a series of her offensive tweets were resurfaced—the pair are enjoying not one, but two rainbow babies.

They revealed June 28 that newborn baby Wren Alexander Stephens—grown with the help of a "compassionate surrogate", Teigen noted—joined his big sister Esti, 5 months, to round out the impossibly photogenic fam. 

"Our hearts, and our home, are officially full," the Chrissy's Court star shared of her two newest offspring who, like older siblings Luna, 7, and Miles, 5, have Dad's given surname. "And to our Jack, we know both their angel kisses are from you."

For every list touting all the times the Lip Sync Battle star, 37, took a playful swipe at her husband, there are countless other reasons the couple are as well-matched as they appear in their family photos. 

For starters, the twosome haven't fallen victim to the competitive nature that dooms other Hollywood pairs. As Teigen began collecting magazine covers, book deals and hosting gigs, her multi-hyphenate spouse (hello, EGOT!) was "supportive and happy and proud," she told Cosmopolitan. "I'm with someone who is totally secure in himself. He's not trying to be anything other than what he is."

But for Teigen's sake, the Ivy League grad will happily binge watch The Real Housewives of Dallas. She, in turn, will dive into an MSNBC report he finds enthralling.

More than a decade in, her top takeaway is surprisingly simple. The key to relationship success, she told In Style in 2017, is to "make each other's loves and needs feel important."

Before their Italian vows, before Teigen gushed to E! News about "absorbing" all of Luna's "new little steps and new moments" and how Miles is "just the happiest bug," before the loss and the miracles that followed, they were just two attractive people eating In-N-Out burgers in a hotel room.

Back in 2006, rising star Legend (he already had two albums and three Grammys to his name) was on the hunt for a model to film his "Stereo" music video when the director suggested a little-known 21-year-old Billabong stunner.

Arriving on set—precisely seven years and one day before their eventual wedding date—Teigen walked into Legend's dressing room to introduce herself. "He was ironing in his underwear," she recalled to Cosmopolitan. "I said, 'You do your own ironing!?' He said, 'Of course I do.' I gave him a hug."

Throughout the 14-hour shoot, the pair maintained that comfortable banter. "We spent the whole day dancing together, grinding together," Legend told The Guardian. "And, uh, we made a music video."

Teigen, as always, was more forthcoming. After returning to his hotel room for a fast food feast, she recalled to Cosmopolitan, "We hooked up."

So, okay, it wasn't love at first sight. But, as Legend told L.A. Confidential, he's far too cautious to dive in like that. "I wasn't like, 'This is the woman I'm going to marry,' from day one," he said. "For me, I'm the kind of person who needs to grow into that feeling."

In other words, their romance was relatable from the start, if you ignore the whole meeting-on-the-set-of-a-music-video thing—and that their main obstacle was the musician's upcoming tour.

As they kept in contact via text and phone chats, Teigen was careful not to mention the other women Legend posed with on the red carpet. "I let him be himself for a while," she explained to Cosmopolitan. "The worst thing you can do is try to lock someone like that down early on, then have them think, there's so much more out there. I played it cool for a long time. Never once did I ask, 'What are we?' Marriage was never my goal, because I've never been very traditional. I was just happy to be with him."

And Legend was just happy to keep receiving her witty missives. "I started to fall in love with her over the phone because she is good with those 140 characters," he joked to Entertainment Tonight in 2016. "We were texting a lot, and I started to see her sense of humor. We would talk on the phone, and I started to fall in love with how engaging and witty and funny she is."

The chemistry was even better face-to-face. When they started dating in earnest post-tour, "I think that's when I really started to know that this was the kind of person I wanted to be around a lot," he said. "Once we started spending more time together between tour stops and all this other stuff, we realized we had such a connection—and then it blossomed into a marriage and a baby."

Of course it wasn't quite that easy. After five years of dating, including one half-hour split that Legend chalked up to being stressed and busy on tour—"I was just like: 'I'd be happier single right now,'" he told The Guardian, "and she was like: 'No'"—the singer-songwriter dropped to one knee during a December 2011 holiday in the Maldives.

"There was no big grand speech or anything," Teigen shared on her now-defunct talk show FABLife, "it was just very lovely and sweet."

Tasked with putting together vows for 125, including Kanye West, Stevie Wonder and Brooklyn Decker, they settled on Lake Como, Italy, the same spot they visited early on in their romance.

"A boat tour guide took us to a little spot on the lake and told us to make a wish," Teigen explained on Instagram. "I asked for this to be the man I marry and have children with. I think John asked for the most perfect bite of cacio e pepe. Both came true, and here we are."

Two days before their Sept. 14, 2013, nuptials, they took to the famed lake to film a steamy black-and-white music video for Legend's hit "All of Me," penned for his bride. It would go on to earn two Grammy nods, a spot at countless wedding receptions and provide a prime opportunity for Teigen.

Taking to Twitter, she wrote, "2 grammy noms for @johnlegend no one has congratulated me for being the inspiration behind 'all of me.' without me there is no all of me." Legend didn't miss a beat, responding, "@chrissyteigen who told you this song was about you?"

So basically the pair aced the happily ever after part.

Their transition into the husband-and-wife phase of their coupling was so seamless that Legend admits to being confounded by those that struggle. While watching a reality show about the first year of marriage, he told DuJour, "We couldn't understand why things change so much when people get married." Teigen agreed it would take something drastic to unravel their union. "Honestly, you would have to cheat," she said. "That's the only reason I could foresee us needing couple's therapy."

They endured the "for worse" portion of their vows early on.

Tired of being quizzed about when they'd start producing little Legends, the model, who's said she's so open "sometimes I don't ever realize I'm oversharing," divulged the details of their fertility struggle. "I will say, honestly, John and I are having trouble," she confessed on her talk show. "We would have kids five, six years ago if it'd happened. But my gosh, it's been a process!"

Two rounds of IVF brought them Luna, who, Teigen said, "sat inside me like a little cross-legged Buddha facing toward my back for nine months." During delivery, Legend played DJ and as the first lyrics of "Superfly" sounded, Luna arrived. "I immediately put her on my chest," she told Glamour. "And she had a face! I was so happy."

That bliss quickly faded. Teigen suffered through undiagnosed postpartum depression for months after Luna's April 2016 arrival.

"Most days were spent on the exact same spot on the couch and rarely would I muster up the energy to make it upstairs for bed," she described in an essay for Glamour. "John would sleep on the couch with me, sometimes four nights in a row. I started keeping robes and comfy clothes in the pantry so I wouldn't have to go upstairs when John went to work. There was a lot of spontaneous crying."

And plenty of comfort from Legend. "He is not the goofiest guy, but he has gone out of his way to indulge my sense of humor," she wrote. "When I was having a good day, he would go to Medieval Times with me and put on the crazy period hat! He sees how much my eyes light up when he does that stuff, and he knows that's what I need. I know he must look over at times and think: My God, get it together. But he has never made me feel that way."

That support—paired with Luna's general overall adorableness and Teigen's desire to have a son because "they say that boys just love their mamas"—is what made the Cravings author eager to dive back into pregnancy. "I really want to just knock 'em out," she told E! News. "That's my dream, I want to just be pregnant kind of for the rest of my life."

Well, not quite. "But the rest of my fertile life," she clarified. "So we'll see."

She was prepared should she face postpartum again. "Do I worry about it with this little boy? I do," she admitted. "But I also know that when it does happen—if it does—I'm so ready for it. I have the perfect people around me for it. That's why I stand for a real core group of people around me."

Heading up Team Teigen, as always, is the "Love Me Now" singer. Sure, she's the first one to take a dig at Legend, "but I will say he is an amazing human being," she told E! News.

To her, his list of attributes is lengthy. "He has seen me at my worst, but I will say I don't think I have ever seen him at his," she has said. "He's exactly as compassionate, patient, loving and understanding as he seems."

As if to prove that, he gave E! News his take on Teigen's postpartum confession, revealing how blown away he was by her op-ed. 

"She showed me the drafts when she was writing it and I knew it would mean a lot to a lot of women for them to see that," he told E! News at the time. "By acknowledging the pain that she's going through, in doing that she also acknowledges the pain that a lot of women go through after they have a child. A lot of people don't want to talk about it. A lot of people feel alone when they're going through it and for her to let people know that they're not alone, I think was really powerful." 

No matter what she decides to tackle next, he'll be hollering from the sideline. "I'm her biggest cheerleader," he told Vanity Fair in their December 2019 cover profile. "I always think she should do more." And if some days she'd rather dig into a Real Housewives marathon or recreate TLC's Four Weddings on a random weekday, well, he's down for that too. 

Because at the end of the day, he knows he got a pretty good draw. "She's the one. It's clear!" he raved to People of his wife of nearly a decade. "We have great chemistry. She makes me laugh all the time. She's a wonderful mother. She's my best friend."
