Congratulations! Donny Osmond revealed son Christopher is going to have a baby girl when he and wife Debbie Osmond attended the 29-year-old’s gender reveal party on Sunday, May 31.

“The Donny and Debbie family is growing! After one sweet granddaughter and nine wonderful grandsons, the exciting day for the gender of grandbaby is finally revealed,” the 62-year-old musician wrote via Instagram next to a clip of him and Debbie, 61, shooting pink powder out of a cannon. “Congratulations to our sweet kids. Chris and Alta. We love all three of you. Debbie and I are so happy. #FamilyIsForever.”

This new addition to the family will be the first child that Chris and his wife have together. The couple told their friends on social media that they were expanding their brood on the same day they had their gender reveal party.

“We’re so excited to announce we’re adding a new member to the tribe!” Chris wrote on Instagram. “And to our big surprise, it’s a GIRL. Here comes the next chapter in life called parenthood! Coming November.”

Their news couldn’t have come at a better time. In May, Chris and Alta also celebrated their second wedding anniversary. “I seriously lucked out with the most amazing wife/best friend in the world. You ask anyone and they’ll say Alta is the most loyal person out there,” Donny’s son gushed on May 11. “I couldn’t agree more. I’m so excited to grow old with you and witness the amazing things you’re going to accomplish in this life.”

In 2017, the two lovebirds tied the knot at the same place the Masked Singer alum met Debbie: the Sundance Mountain Resort. When Donny attended the event, he took a video of the bride and groom’s first dance and shared it on Facebook.

“WOW — what a weekend!” the “Puppy Love” singer said at the time. “There are no words to describe the incredible past few days we’ve enjoyed with the family. First Chris and Alta’s wedding, then Mother’s Day and skyping with Josh from Italy … do weekends get any better than that?”

Aside from Chris, Donny is also a proud dad to his sons — Donald, 40, Jeremy, 38, Brandon, 35, and Joshua, 22.
