Watch: Britney Spears Pulls Colton Haynes On Stage & Straps Him in a Harness

Our ever-handsome cover star Colton Haynes attended Britney Spears' Piece of Me concert in Vegas last night, and was pulled onstage by the singer and strapped into a leather harness to serve as her "bitch" during her performance of "Freakshow."

In a video of the event Haynes posted on Instagram this morning, Britney gushes, "That was so much fun, thank you so much for coming up here and dancing with us!"

Still in shock haha. Made my Vegas debut with @britneyspears @phvegas #PieceofMe #TheAXIS What the hell just happened!!!??? So cool!!!

"You're an amazing dancer," she continued. "Call me anytime. Everyone's so beautiful... his ass!" she proclaimed, proving that Brit is just as thirsty for the soon-to-be Scream Queensstar as the rest of us.

And amazing at dancing he is. In a recent Snapchat, Haynes showed off his remarkably skillful booty roll capabilities, and a fan has graciously edited the video into a 45-second masterpiece for our viewing pleasure:

Also at the concert last night, Britney performed a fourth single off of Glory called "Do You Wanna Come Over?" Take a peek below.
