Bookmakers also believe Bristol belle is a sure thing for tonight's final

Josie is being backed as if defeat is out of the question ahead of tonight's Big Brother 2010 final after being tipped for success by three of her former housemates.

Last week's four semi-final evictees were all asked to give their verdict on who will be the last person standing and Bristol belle Josie got the nod from all but one.

"I'm going to go for Josie to win and then for second it's a toss up between Dave and Mario but I'll just go for Dave," said Corin on the official Big Brother website.

John James added: "Obviously I think Josie is going to win and that's who I want to win. Then I'm going to go for Mars, as he wants it so much and is such a genuine bloke."

Sam elected to provide drawings of his finishing order, with a thumb representing Josie in first place and a mole for Mario in the runner-up slot.

Only Steve bucked the trend, commenting: "I'm going to go against the grain and say perhaps the Glory (Dave) will triumph, followed by Brizzie and Mazza."

Josie is currently a top-priced 1/16 with William Hill to be crowned champion of Big Brother 11, with Dave 14/1 at this firm, Mario 16/1, Andrew 40/1 and JJ 50/1.

The betting over who will be the last man standing has been much closer but late support has seen Dave cut to 8/11 favourite with bet365, who offer 12/5 for Mario to be the top man, 11/2 Andrew and 14/1 JJ.

Three of the four ex-housemates thought that Andrew would finish in fifth position, but he can be backed at 2/1 with Hills for the wooden spoon tonight as JJ is a firm favourite at 8/11 for that market.
