There's a little Backstreet Boy or Girl on the way for A.J. McLean!

The 34-year-old singer and his wife of seven months, Rochelle Karidis, are expecting their first child together.

McLean announced the news himself over the weekend with a personal YouTube message to his fans.

"We wanted to share with you for the first time something very special, we're having a baby," the excited couple proclaimed in the video.

McLean is the fourth Backstreet Boy member to have kids. Brian Littrell, Howie Dorough and Kevin Richardson all have sons too.

Congrats to the happy couple!
