Alfonso Ribeiro is going to be a dad for the second time.

The "Dancing with the Stars" contestant revealed his wife, Angela Unkrich, is pregnant with the couple's second child after finishing his routine on the dancing competition on Monday.

"My son, it's his first birthday today, so I'm so happy that he's here with me. And as a wonderful present, my wife and I decided to get him a little brother or sister," Ribeiro said.

"We're having a baby! I wanted to announce it here on the show because I just wanted to say thank you to all the fans and say I love my wife."

Ribeiro and Unkrich married in 2012 and welcomed their first son, Alfonso, in October 2013. "The Fresh Prince of Bel Air" star also has one daughter, Sienna, from his previous marriage to Robin Stapler.
