Jessica, 27, and Cody, 33, popped a giant black balloon during a Monday brunch while surrounded by their family and closest friends. As shown on Instagram Live, pink confetti exploded from the balloon and everyone cheered.

"ITS A GIRL!!!" Jessica captioned a sweet photo of the smiling couple on Instagram after learning the big news.

Cody also shared a series of images from the brunch on Instagram in which his six-year-old daughter Paisley from a previous relationship can be seen crossing her arms in the background.

"Paisley wanted a brother..." Cody wrote alongside the photos.

The pair's former Big Brother housemates Mark Jansen and Elena Davies attended the party, as did Big Brother's Season 20 runner-up Tyler Crispen and his girlfriend Angela Rummans, who placed fourth on this past season.

The couple said, "I do," during an outdoor ceremony at The Chateau Le Dome at Saddlerock Ranch on Sunday, according to People, and Jessica called the romantic black-tie affair with some Texas flair a "daydream."

Not only were Elena and Mark guests at Jessica and Cody's wedding, but Big Brother alum Corey Brooks was also in attendance as well as former The Amazing Race team Conor Daly and Alex Rossi. The Bachelor's Season 21 winner, Vanessa Grimaldi, also served as one of Jessica's bridesmaids.

Jessica and Cody met and fell in love while filming Big Brother's nineteenth season in 2017, and they later went on to win The Amazing Race's 30th edition.

After winning $1 million on The Amazing Race, Cody proposed marriage in February 2018, right before Valentine's Day.

Cody popped the question on the top of Runyon Canyon in Los Angeles, CA, and seven months later, Jessica announced she's pregnant.
