Backstreet Boys 'looking into' Las Vegas residency

LOS ANGELES, March 8 (UPI) -- The Backstreet Boys may join fellow 90s stars Britney Spears and Mariah Carey in Las Vegas.

Singer A.J. McLean revealed he and the band are interested in a Las Vegas residency in an interview with Entertainment Tonight at the Los Angeles premiere of Grimsby.

"We are talking about it. We are looking into it right now and we'll see," the 38-year-old singer said. "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 [also] doing my very first solo project," he added. "There's a lot of things going on this year."

McLean and bandmate Kevin Richardson took their managers to see Spears perform and "do some recon for a possibly residency" in February. Spears kicked off her residency at The Axis at Planet Hollywood in 2013 and will perform there through 2017.

"We wanted to go see the production, see the show, catch up with our old friend Britney," McLean said. "She was amazing as usual! 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."

Spears shared a photo from McLean's visit on Instagram, writing, "Huge confession... biggest @backstreetboys fan! Tonight was truly a dream for me." The 34-year-old singer previously dated Justin Timberlake, who was a member of Backstreet Boys rival 'N Sync.

McLean, Richardson, Howie Dorough, Nick Carter and Brian Littrell formed the Backstreet Boys in 1993 and last released In a World Like This in 2013. The band is working on their ninth studio album and will embark on their Backstreet Boys Cruise tour May 10.
