Sophie is tipped to win Friday night’s Big Brother final, in what promises to be a poignant show following Channel 4’s decision to axe the programme.

The 20-year-old is one of five remaining housemates in the final showdown, alongside Siavash, Rodrigo, David and Charlie.

William Hill made Sophie the 1/4 favourite to win and are also offering 8/1 odds that the glamour model will pose for Playboy in 2009.

The bookies put David as the hot favourite to be booted out first on Friday night at 4/9.

Sophie, who had a relationship with curly-haired Kris while in the house, is also Paddy Power’s favourite and the bookmaker has chopped her odds from 5/4 to 2/9.

Meanwhile, former BB10 contestant Noirin has given Charlie her backing, saying: “I hope he wins, fingers crossed.

“He’s kept us entertained from the start to the end. He’s not been afraid to speak his mind, he’s funny, he’s been a nice guy as well. People say he’s too nice, but I actually think he’s a genuinely nice guy.”

Channel 4 said last week that it would not renew its deal with programme-makers Endemol when it expires next year, making next summer’s 11th series the last for the broadcaster. Disappointing ratings for the latest series have scraped around the two million viewers mark, compared with 10 million in the show’s heyday.
