Ringtone favourites Robbie Williams and Little Britain's David Walliams are set to team up to become an unlikely pop pairing.

The Sun reports that good friends Williams and Walliams have been meeting together, discussing ideas and writing, with the possibilities of the results going on Robbie's next album.

"It began as nothing serious but it has turned out that they work well together. They make each other laugh, set each other off."

"From that, the songs have started flowing. Nothing official has happened yet but if the songs are good enough, Robbie has said he'll use them on the next album," the paper's source said.

Walliams was in the crowd on Saturday night as Robbie spent the evening previewing his new album to a couple of thousand fans in a cosy club setting in central London.

The former Take That star played songs off the new album as well as classic Robbie Williams tracks such as Rock DJ and Angels.

His new album, Intensive Care, is due for release at the end of October.
