If there's one thing that Britney Spears has no qualms about during the "Freakshow" portion of her Piece of Me residency in Las Vegas, it's making you her very own b*tch.
On Saturday night, the 35-year-old pop star invited Howie Dorough of the Backstreet Boys on stage with her and things got a little bit naughty.
Spears turned up the heat by getting Dorough strapped up in a harness and then whipped him and instructed him to crawl on all fours during the Blackout cut.
"Everyone give it up for Howie from the Backstreet Boys," she yelled at the crowd after the number. "Thank you so much for coming up and dancing with us, baby."
The Backstreet Boys have a residency in the same venue as Spears. The group also performed Sunday night with Florida Georgia Line at the ACM Awards.
