After the juicy revelations about prostitutes and masturbation in the title, it seems fans are in for a celebrity surprise too as Ricky Gervais will appear as himself in GTA IV as an stand up act within Liberty City's comedy club.

Apparently to unveil brand spank new material created especially for Rockstar's much hyped gangster title, Gervais said:

"It's a first - which always interests me. It was shot in New York, my favourite place in the world, and I got to wear a tight lycra suit as part of the digital process. No, hold on, that wasn't so good."

Describing the cameo as a "big deal", Gervais acknowledged the importance of games in the entertainment industry:

"Unfortunately they captured the whole horror, except I look slightly tougher. It's seriously a big deal, though. Games have outsold Hollywood for the past few years so it's nice to be a small part of that."

The game will be released on Xbox 360 and PS3 on 29 April.
