EXCLUSIVE: A.J. McLean Says Backstreet Boys Are 'Looking Into' Las Vegas Residency

Get excited, all you Backstreet Boys fans!

ET caught up with A.J. McLean at The Brothers Grimsby premiere in Los Angeles on Thursday, when the 38-year-old singer said the boy band is definitely interested in a Las Vegas residency a la Britney Spears and Jennifer Lopez.

"We are talking about it. We are looking into it right now and we'll see," McLean exclusively told ET. "We'll see what happens! Right now, we're actually back in the studio making our ninth album. If anything transpires it'll probably come after our brand new tour, and I'm doing my very first solo project. There's a lot of things going on this year."

McLean said he and his fellow BSB bandmate, Kevin Richardson, have already done some research into a possible residency when they checked out Spears' Britney: Piece of Me show late last month.

"Kevin and I went out there with our managers to do some recon for a possible residency," McLean revealed. "We wanted to go see the production, see the show, catch up with our old friend Britney."

"She was amazing as usual!" he gushed. "She's such an amazing performer -- she's so sweet. She has not changed a bit. She's still just a sweet little Southern belle."

He also obviously couldn't complain about getting chosen from the audience to be in her "Freakshow" number, when he was playfully chained and handcuffed.

"Her little fangirl moment on stage was kind of priceless," McLean smiled. "I was a fan just being there, and then she pulled me on stage and did what she did with me, which was fun! My wife was actually super jealous that she wasn't the one who got spanked."

ET chatted with McLean in January at the Fifty Shades of Black premiere in Los Angeles, when he teased what fans can expect from the Backstreet Boys' new music.

"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," he exclusively told ET. "So for all the ladies out there, we're all grown men."
