Actress Jennifer Lawrence was left squirming with embarrassment during an appearance on U.S. late night show Conan on Tuesday (05Feb13) when the host tracked down footage of an early Tv role she'd rather forget.

The Oscar nominee played a school mascot in an episode of crime drama Monk and had to spend the show dressed up in a cougar costume, running up and down a basketball court.

As Lawrence held her head in her hands, host Conan O'Brien announced, "You're now nominated for an Academy Award; let's see some of this fine work that you did."

When the cameras turned back to her after the clip was shown, the actress was curled up in her chair, trying to hide her shame.
