It's a boy for Wes Chatham and Jenn Brown!

Just days after The Hunger Games star, 37, and his TV personality wife, 34, announced they are expecting baby No. 2, the couple announced the gender at their son John Nash's first birthday party.

To unveil the big news, the pair opted for a smash cake, which was blue on the inside and topped with a big “1” to celebrate the big brother's special day as well.

“We decided to reveal the sex this way because the timing just worked out perfectly,” Jenn told People. “Our doctor told us the date we would have the results of our blood work back and it was just a few days before Nash’s first birthday. We figured this would be way more fun than the doctor just reading it to us over the phone."

Believe it or not, the mom-of-one was convinced she was having a girl before cutting into the sweet treat. “This pregnancy started off for me very differently than the first. I was sick the first few months, and with Nash, I had no morning sickness,” she explains of the little bundle of joy, who is due in May. “For that reason, I thought we were having a girl. I was very surprised when Nash dug into the cake and it was blue.”

Wes and Jenn married in April 2012 after a seven-month engagement. They welcomed son John in November 2014.
