Backstreet Boys alum, A.J. McLean dishes out on the boys’ next album which will be sexier and a little bit “grown up” as he teases fans as they will be part of the upcoming movie Fifty Shades of Black.

"We're actually going back to old Backstreet -- more of that pop R&B, a little bit more grown up, a little bit more sexy," McLean told ET. "So for all the ladies out there, we're all grown men."

Not only that our beloved Backstreet Boys are all grown up, but many of them are all fathers. According to Entertainment Tonight, the 38-year-old singer reveals that he was happy to have a date night with his wife Rochelle while their 3-year-old daughter, Ava Jaymes, was tucked away in bed at home.

"[Date nights] keep that marriage going strong," McLean said. "We have the best marriage anyways. We have the best baby girl too."

Meanwhile, the singer and performer also admitted to ET that his little girl has love for music and shows strong desire in singing and dancing.

"She's definitely not shy," McLean shared. "She loves to sing. She loves to dance. She loves all of my music. I mean, whether it's Backstreet or solo, which has been great except one of her favorite songs is actually called 'Sex,' which is a little weird. She doesn't really know that it's about that, thank God, but it's a little awkward for me."

 Meanwhile, the pop star has also other gigs he's busy with, as he dished out that he will be with Gigi Hadid on Lip Sync Battle next month. In addition to their partnership on Lip Sync Battle, the Victoria's Secret model will be featured on BSB's first music video for their next album.
