Lady GaGa and Britney Spears are reportedly planning to record a song together.

Gaga apparently suggested a collaboration after being introduced to Britney at the Grammy Awards.

A source told the UK's Sun: "GaGa has made no secret of just how much of a Britney fan she is. She has even admitted she used to have posters of her on her wall and she was a great source of inspiration when she was a struggling songwriter. She was delighted when she found her dad chatting away to Britney at the party. He introduced them and the three of them were locked in conversation for ages."

"At the end of the chat, they exchanged numbers and agreed to go into the studio and work on music together as soon as GaGa finishes her 'Fame Monster' tour."
