A.J. McLean and his wife, Rochelle DeAnna McLean, are expecting baby No. 2!

The Backstreet Boy announced the happy news via social media on Monday, Sept. 5, with a pic of four different-sized Jordan sneakers lined up next to one another.

“So the Mclean family wil [sic] be expecting a new addition to the family next spring!! #laborday! Ha get it "labor" day! I'm a goof! #avaisgonnabeabigsister #baby2! Keep u all posted!! We're so excited,” he captioned the cute photo.

The 38-year-old musician and his wife were married in 2011 and are already parents to a three-year-old girl named Ava. A.J. is the only member of the band to have a daughter as Nick Carter, Brian Littrell, Kevin Richardson and Howie Dorough all have boys. Once the sex of the McLean’s baby is revealed, we’ll know if Ava will get the company of another little girl in the Backstreet family.
