It’ll be a baby girl for Jessica Graf and Cody Nickson!
The Big Brother stars, who got married on Sunday, announced the sex of their first child on Instagram Live Monday during a brunch attended by their family and friends, including former housemates Mark Jansen and Elena Davies, fellow Big Brother alum Angela Rummans and season 20 runner-up Tyler Crispen.
Nickson, 33, and Graf, 27, found out they were expecting a daughter after the pair, who met during Big Brother 19 in 2017 and went on to win season 30 of The Amazing Race, popped a giant black balloon that exploded with pink confetti. In addition, they learned a baby girl is on the way when they sliced into a cake that had pink colored filling inside.
Nickson is also dad to 6-year-old daughter Paisley from a previous relationship.
