Gianna shared similar news in her post:

“This came as a big surprise to us and I’m nervous HELL YEA but I’m super super excited to grow this little bean into a cute lil mini me (or mini Hayden),” she wrote. “God has a way of surprising people when they least expect it. Adding another baby to the ‘AYTO’ fam. August better come quick!”

Hayden and Gianna’s baby will be the third to be born to an ‘AYTO’ couple. Season One’s Ethan and Amber Diamond welcomed a daughter in 2014. The couple is expecting their second child in June.

‘AYTO’ fans may remember that Hayden and Gianna weren’t a perfect match on their season, nor did they ever pair up at a matching ceremony. However, the couple began dating after their season wrapped and Gianna even showed up to the reunion show rocking a “promise to get engaged” ring from Hayden. (Apparently, that “perfect match algorithm” doesn’t always get it right, eh?)
