The Only Way Is Essex star Amy Childs is currently the 5/1 favourite to win Celebrity Big Brother 2011 - despite the fact that Channel 5 has yet to confirm any official line up for the reality series. Meanwhile soap star turned pop star Martine McCutcheon is also tipped to do well as the 6/1 second best bet.
Other stars in Paddy Power's current Celebrity Big Brother 2011 winner's market include Max George from boy group The Wanted and former Boxer Ricky Hatton.
Some of the less likely stars to appear in the show this year are chart topper Tinie Tempah and Prince Harry's on and off again girl friend Chelsy Davy.
There's unfortunate news for axed Sky Sports presenter Andy Gray meanwhile, who is the 100/1 favourite to win the show. Even if really is thinking about taking part it doesn't look like it'll do him much good!
US actor Charlie Sheen is the 12/1 favourite with the bookmakers.
Celebrity Big Brother 2011 starts in August this year on Channel 5. News about the new presenters and line up is not expected until July.
