Giannina Gibelli and Blake Horstmann aren't going in blind when it comes to the sex of their baby. 

Rather, the pregnant Love Is Blind alum and Bachelor Nation star revealed they are expecting a baby boy during a live gender reveal party.

"A little dude," Blake exclaimed while raising up the blue knitwear during the Feb. 15 Amazon Live. "The Horstmann name lives on!"

Giannina—who announced her pregnancy back in November—was equally as thrilled, adding, "I'm so excited! He's made me feel so good. He loves his mama."

She then quipped, "I can't believe I can say ‘he'!"

And while the couple—who celebrated their second anniversary in December 2023—are more than happy to be having a boy, they did admit the sex came as a shock to them. 

"We didn't think it was gonna be a boy," Blake confessed. "Neither of us... I thought I was gonna be a girl dad."

Even with the surprise, they've already managed to pick out a name.

That is "unless he pops out, and we're like, ‘No, that's not his name,'" Blake explained. "It's a strong name, and it's unique."

And the baby's sex isn't the only detail Giannina and Blake revealed during the live. The pair also shared their son's due date is around Apr. 3, 2024—a date that already holds special significance to their lives.

"We put in the conception date and everything into a little calculator," Giannina shared. "And [the due date] came up as my birthday. Out of all the days—365—what are the odds it came up as my birthday? We were just like, ‘Alright, this is so meant to be.'"

Back in January 2022, E! News confirmed that Bachelor Nation's Blake Horstmann and Giannina Gibelli were dating. 

After meeting on Paramount+'s reality show All Star Shore, the pair realized they wanted to be more than just co-stars. 

"I've never watched the Bachelor franchise or any of that so I didn't know who he was," Giannina told E! News at iHeartRadio's KIISFM Wango Tango. "He seemed familiar to me and he just flashed his big ole smile at me and that's how I met him right on the beach."

It wasn't until June 29, 2022—the day All Star Shore premiered—when Blake and Giannina confirmed their relationship by going Instagram official. 

"All creds go to @allstarshoreofficial," Giannina shared on Instagram when posing with her man. 

The couple travels to Blended Festival in Nashville where Blake performed a DJ set at the two-day music, wine and culinary festival presented by My Wine Society.

"He's very respectful, but I don't think that they know just how funny and spontaneous and dedicated he is," Giannina told E! News when describing Blake. "He's doing his DJ gig now and just watching him reach all these new heights and all these goals, I don't think a lot of people know that he has it in him, but he definitely does."

 

PDA alert! 

"Happy…Just so damn happy @gianninagibelli," Blake shared on Instagram with a collage of photos. 

"My worst kept secret," Giannina captioned on Instagram. "See why I have been so happy this year on @allstarshoreofficial @paramountplus."
