Alfonso Ribeiro’s wife is expecting their second child. The Fresh Prince of Bel-Air actor revealed his and wife Angela Unkrich’s happy news after his latest performance on Dancing with the Stars last night when he wished their son Alfonso Jr. a happy birthday and announced the 12 month old is going to have a sibling. The 43-year-old star – who scored four nine out of 10s for his rhumba with partner Whitney Carson on the dancing show – told presenter Erin Andrews: ”My son, it’s his first birthday here today. I’m happy that he is here with me. And as a wonderful present, my wife and I decided to get him a little brother or sister. So we’re having a baby. I wanted to announce it here on the show, ’cause I just want to say thank you to all the fans and I love my wife.” Alfonso’s newborn will be his third child as he also shares custody of his 12-year-old daughter Sienna with his ex-wife Robin Stapler, who he filed for divorce from in 2006 after four years of marriage.
