When Anne Hathaway appeared on 'Lopez Tonight' (weeknights, 12AM ET on TBS), she reminisced about working with George Lopez in 'Rio.'

In addition to voicing characters, they both sang in the film. "'Rio' was not the first time that Anne Hathaway was singing," noted Lopez. And he wasn't referring to the Oscars. Before showing the clip, he added, "This will bump up your street cred."

Unbeknownst to Hathaway, the show's producers had dug up footage of a teenage Anne singing, dancing and even rapping at Paper Mill Playhouse in Millburn, N.J.

Horrified, Hathaway screamed, "Oh, no!!" and then began to laugh. "Thank you, Paper Mill Playhouse," she said sarcastically.
