Aca-scuse me?

Rebel Wilson floated into the MTV Movie Awards on Sunday night to introduce a new clip from Pitch Perfect 2 – and say she’s sorry for an R-rated moment in the film.

After her costars said she couldn’t be there because she was too tired from “jet lag,” Wilson, 29, crashed the stage wearing angel wings and black spandex, admitting she was actually hungover.

“I actually want to say something from my heart tonight,” she began. “Dear people of the world, I would like to take this opportunity to formally apologize for my actions on the set of Pitch Perfect 2, including the moment when I accidentally showed my girl power to the president of the United States.”

As seen in the sequel’s trailer, her character Fat Amy got the Barden Bellas in serious trouble after flashing President Barack Obama during a particularly NSFW performance of “Wrecking Ball.”

“Yeah,” she clarified Sunday, “by girl power, I do mean vagina.”
