Lady GaGa is a huge fan of Rebel Wilson.

The 'Pitch Perfect' star performed Gaga's 'Edge of Glory' when she appeared on 'The Tonight Show with Jay Leno' on Monday (01.10.12) and the singer was so excited she tweeted about it.

Lady Gaga posted a link to the video of Rebel singing and wrote: ''i bet she had no idea I'm a HUGE fans. this is so amazing i peed my pants. Rebel Wilson singing ''The Edge of Glory'' (sic).''

It was recently revealed that Lady Gaga is planning a jazz album with Tony Bennett.

The 'Judas' singer previously teamed with the crooner for a version of 'The Lady is a Tramp' from his 'Duets II' album and they enjoyed working together so much, they want to record a whole album.

Tony said: ''Of all things, she called me from New Zealand and said, 'I want to do a jazz album with you' and I said, 'You got it!'

''We're gonna do a jazz album with Marion Evans, a big swing band, and I'm looking forward to it because a lot of people don't know it, but she's a phenomenal jazz singer.''
