Britney Spears might have dated a member of *NSYNC, but on Sunday she got up close and personal with one of the Backstreet Boys. During her Las Vegas Piece of Me concert, the 35-year-old superstar invited Howie Dorough on stage for a provocative performance of "Freakshow," and things got steamy. Howie, fresh off of his performance at the ACM Awards, happily crawled around on all fours while Britney whipped him. "Thank you so much for coming out here and dancing with us," Britney said before signing a t-shirt for him. "Thank you. Bye, baby. Everyone give it up for Howie!"
The Backstreet Boys are currently headlining their own Vegas residency, which makes it easy for them to pop by Britney's show. In February, A.J. McLean hung out with her backstage and had nothing but good things to say about her performance. "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."
