Ooh, he's such a laydee! Yes, behind the red lippy, rag-rolled curls and frilly dress it's that famous prankster, Robbie Williams.
Better known for showing off his pants and numerous tattoos, the Robster's covered them up for the Little Britain Emily Howard sketch.
He's a massive fan and mucked in with Matt Lucas and David Walliams for a special Comic Relief sketch.
Other celebs are jumping on board too - Vicky Pollard's going on agony show Trisha and Sir Elton John's going to be the second gay in the village, all in aid of a good cause.
- The special sketches can be seen on the Comic Relief Little Britain DVD, which will be available from HMV, www.rednoseday.com and all BBC shops from 14 February. The theme for this year's Red Nose Day (11 March) - Big Hair and Beyond - Just Do Something - is about changing the way you look to transform someone else's life.
