Newlywed A.J. McLean is going to be a dad! The Backstreet Boy, 34, and wife Rochelle Karidis announced the happy news in this video, saying, "I just wanted to say thank you guys for all your love and support . . . Because we love you all so much, we wanted to share with you -- for the first time -- something very special. We're having a baby!"

The couple tied the knot in December at the Beverly Hills hotel. This is the first child for both McLean and Karidis.
