AJ McLean and his wife, Rochelle DeAnna Karidis, are expanding their family. The Backstreet Boys band member announced on Instagram back in September that he and his wife are expecting their second child, and on Monday, AJ revealed that he's having another girl. At the We Are X premiere in LA, the boy bander told ET, "A lot of girls in the house! I will take that over testosterone running around the house, to be honest with you." This will be the couple's second child, having welcomed their daughter Ava Jaymes back in November 2012. We can't wait to see even more cute pictures of the Backstreet Boys's kids.
