Lindsay Hubbard is creating extra special fireworks with this announcement.

The Summer House star is expecting her first baby with her boyfriend, she shared in a Fourth of July message.

"WE’RE PREGNANT!!!!!" Lindsay, who has not publicly identified her partner, wrote on Instagram alongside photos of her growing baby bump and sonogram. "I truly believe the universe has a bigger plan and this is it!"

The Bravo star's new chapter comes nearly a year after she called off her engagement to fiancé Carl Radke.

And although the 37-year-old is keeping her new boyfriend's identity a secret for now, she recently told E! News that he's an "incredible" man.

"We have a very sweet, caring and loving relationship that I truly cherish," she shared in June, noting that she's not rushing into marriage. "I got rid of any and all timelines considering all of my past timelines have blown up in my face."

"I'm really just enjoying my relationship as it naturally progresses," she continued, "and I'm not putting any pressure on next steps until it feels right for the both of us. I hope it eventually does lead to a serious future with him, but if it doesn't, that's okay too."

As for why she's keeping the relationship out of the public eye?

"When we started dating, I really wanted to maintain our privacy for as long as possible," Lindsay explained. "We needed to see how we felt about each other without the whole world chiming in with their opinions or judgements."

"The only thing that truly matters is how we feel about each other at the end of the day," she added, "and I needed space and time to figure that out for myself."

Lindsay also confirmed plans to film the nuptials for season eight of the show. "If we were just getting married with all of our guests and friends that would be one thing," she continued, "but when you're considering the idea of filming it, there's another level of criteria that you have to get checked off."

Exactly two weeks after the split news came to light, Lindsay broke her silence and revealed she's "heartbroken" and humiliated" with how Carl ended things.

"My trust has been betrayed, and coming to terms with that has been difficult for me," she wrote on Instagram Sept. 14. "This was not my decision, and I do not agree with quitting a relationship (at this level) without trying everything possible first. I have spent the last couple of weeks finding my own closure and peace. I am forever grateful to my best friends who have not left my side, and have been picking up the pieces of my heart and life every day from the fallout."
