The 38-year-old singer announced the news on Monday (05.09.16) on social media when he posted a photo of four different sizes of the same Air Jordan trainers.

Sharing the picture on his Instagram, he captioned the image: "So the Mclean family wil 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. (sic)."

The Backstreet Boys singer - who already has three-year-old daughter Ava Jaymes with his wife Rochelle - also revealed he's had baby fever on his mind ever since his daughter was born.

He previously said: "Mommy and Daddy are trying to figure out when we get Mommy Daddy time. We are talking about [baby] number two so it's trying to figure out when and where!"

However, the 'I Want It That Way' hitmaker has no misconceptions about raising a second child as he insisted that while it might be "easier" the second time around, it'll still be a "brand new" process.

He said: "Whatever our next child is, boy or girl, you would think that 'Oh I did it once, I've got it.' No. It's hard. It'll make it easier, but it's still going to be a brand new learning process."

The baby news comes after the Backstreet Boys - who are made up of A.J. plus Brian Littrell, Howie Dorough, and Kevin Richardson - expressed an interest in collaborating with Meghan Trainor again after their one-off special performance on 'Greatest Hits'.

At the time, A.J. said: "She's such an amazing writer, so we're working it out and hopefully when her schedule permits, we can do it."
