Rebel Wilson sings Lady Gaga during talk show appearance

Rebel Wilson showed off her singing skills on Jay Leno's talk show on Monday (01Oct12) by belting out a version of Lady Gaga's Edge Of Glory.

The Bridesmaids star was discussing her new film Pitch Perfect on the Tonight Show and revealed she had to sing during her audition for the role.

She explained, "It's a comedy but you also have to sing in it. They're like, well, she kind of looks like Adele, but can she sing?" before breaking into Lady Gaga's hit while gyrating for the crowd and slapping her breasts, leaving Jay Leno and fellow guest Bryan Cranston stunned.

The Breaking Bad star decided to join in the fun and clapped along with the audience, before Rebel Wilson ended her sing-along by kicking off her shoes and jumping on to her chair.
