The comedian revealed that he doesn't understand why women are attracted to the Oscar-winning King's Speech star and tried to convince the audience that Firth is "evil".
"What you don't know about him is he's very racist. Very, I mean, really nasty stuff." Gervais said. "I've also seen him punch a little blind kitten.

As Firth took to the stage to present the award for 'Best Actress in a Motion Picture (Drama)', he noted that he had seen "some very angry religious people outside with big placards threatening us all with brimstone and pestilence and perdition for our sins".
"What they don't realise is - we have Ricky," he added.
Firth was recently voted the best actor of 2011 in Digital Spy's end of year reader poll.
The actor previously insisted that winning a 'Best Actor' Academy Award for The King's Speech has not changed his life.
