Aubrey Plaza interrupted Will Ferrell's acceptance speech at the MTV Movie Awards, then left the building.
MTV officials confirmed that the Parks and Recreation actress was asked to leave the ceremony after unexpectedly walking on stage and trying to take Ferrell's trophy as he accepted the Comedic Genius Award.
The irreverent awards show is known for its quirky stunts, but it was unclear whether the actress' stage-crashing move was planned.
"What's happening? Are you OK?" Will asked as the actress, who had the name of her new film scrawled across her chest in pen, as she grabbed his trophy with one hand and held a drink with the other.
He held tight to the golden popcorn and the actress returned to her seat in the front row. "Aubrey Plaza, everyone," Will continued. "Just like we rehearsed it."
Rebel Wilson hosted the ceremony and also won two awards: breakthrough performance and best musical moment for her work in Pitch Perfect.
The Avengers was the night's big winner, taking three awards including movie of the year. Silver Linings Playbook also won three awards. Emma Watson received the Trailblazer Award and Jamie Foxx accepted the Generation Award.
The ceremony will air on MTV at 9pm on Monday April 15.
