Natalie Cassidy tipped for Big Brother success

Natalie Cassidy has been tipped as the bookies' favourite to win Celebrity Big Brother 2012 following her performance in the secret mission on the show's launch night.

Bookmakers William Hill have installed the former EastEnders star as 11-4 to be crowned series champion, with rugby star Gareth Thomas second in the betting at 4-1, followed by TOWIE's Kirk Norcross at 9-2.

"Natalie has already endeared herself to the viewers and we think that she is the one to beat at this very early stage," said Hill’s spokesman Joe Crilly.

However it's not such good news for Natasha Giggs and Playboy twins Kristina and Karissa Shannon - who are the outsiders at 25-1.

Natalie won viewers over with her secret mission on Thursday night's show, in which she had to behave as Big Brother instructed, unbeknown to her fellow housemates.

Although she performed well in the task - which saw her claiming that she had posed for Playboy and kissing Frankie Cocozza - she ultimately failed, leaving So Solid Crew's Romeo without his suitcase.

However Natalie fared better on Saturday when model turned body builder Jodie Marsh entered the house and set them a series of physical challenges.

The actress beat Hollywood star Michael Madsen in the first physical challenge, which saw the housemates having to eat a 'bodybuilder's breakfast' of six raw eggs.

Jodie has been setting the housemates physical tasks during the day, with the winners set to enjoy dinner cooked for them by celebrity chef Aldo Zilli.
