Well, technically Kevin's wife Kristin had the baby, although would anyone be surprised if one of the Backstreet Boys actually had a uterus?

 

The Richardson family welcomed their new baby boy, Mason, this past Tuesday at 4:56 AM.

 

According to E! Online, Richardson left the Backstreet Boys a year ago in order to pursue "other interests." This is funny, because it insinuates that the Backstreet Boys are an "interest." Anyway, seriously, congratulations to Kevin and Kristin. Guys, feel free to keep making babies, just don't make any more music.
