Sir Elton John, George Michael and Robbie Williams are to appear in a fundraising Little Britain DVD.

Sir Elton John, George Michael, Robbie Williams, Simon Callow and Trisha Goddard all make an appearance in a new Little Britain DVD to be launched in aid of Comic Relief.

Williams donned a pink dress, fake breasts and curly wig to play a rubbish transvestite in his sketch.

He stumbles into a shop run by David Walliams's Emily and Matt Lucas's Florence, who convince him he'd look good in a frock.

Williams then skips off repeating the catchphrase: "I'm a lady".

In other sketches on the DVD, Vicky Pollard makes an appearance on the Trisha TV show; wheelchair-user Andy gets to meet George Michael, before deciding he doesn't like him; and Elton John is interviewed by "only gay in the village" Daffyd.

Lucas said: "We never thought they would throw themselves into it with quite so much enthusiasm. Some of them, not mentioning any names Robbie, haven't been the same since."

The 45-minute disc will also include unseen out takes from the show and £3.40 of the £4.99 price will go direct to Comic Relief.

The disc, which is out on February 14, was unveiled at yesterday's official launch to promote Red Nose Day on March 11.
