Sometimes it seems like Britney Spears has barely aged a day since she first arrived on the music scene in the late '90s, and Backstreet Boy AJ McLean has certainly taken notice. After visiting Britney backstage at her Piece of Me residency in Las Vegas in February, AJ confirmed to Us Weekly on Tuesday that the pop star is still a showstopper. "Her body's back! She looks fantastic! Britney's back, man," he said. "She's doing fantastic, dude. She was on her A game. She looked good, she sounded good, [and] she was killing it dancing."
AJ, who is set to do a nine-show residency in Vegas of his own with the rest of the Backstreet Boys in January 2017, got a personal backstage tour from Britney, who turns out to be quite the fan of BSB. "Huge confession... biggest @backstreetboys fan!" she captioned her Instagram of the pair back in February. "Tonight was truly a dream for me. #Vegas#PieceOfMe." As you probably recall, Britney was more of an *NSYNC girl back in the day, as she dated Justin Timberlake for three years from 1999 until 2002.
