The Spandau Ballet singer has odds of 2/1 at Paddy Power to emerge victorious from the famous house, just beating Julian Clary and fellow ex-EastEnders star Cheryl Fergison, who are at 7/2 and 4/1 respectively after last night's (August 15) launch show.
Despite the positive reaction to her soap opera task with Fergison, Coronation Street legend Julie Goodyear is only joint fifth on the ranking with odds of 12/1, behind Coleen Nolan on 11/2 and equal with MC Harvey.
The actresses passed their secret mission to fill the house with "scandal, tears and tantrums" last night and won the group a soap-themed party in the garden.
The outspoken trio of Samantha Brick (40/1), Danica Thrall (40/1) and Jasmine Lennard (50/1) are currently the least popular choices with bookmakers.
Celebrity Big Brother continues nightly on Channel 5.
