Sophie Reade has been crowned the winner of Big Brother 10 after being the only girl to make the live final.
The glamour model, who was the bookies' favourite, looked shocked when her name was read out by the show's host Davina McCall.
She hugged runner-up Siavash Sabbaghpour and shook her head in disbelief.
Sophie, 20, from Cheshire, told McCall: "I never thought I'd win. I didn't think I'd get on the show, let alone win. I've never won anything in my life."
The model, who wears a 30GG bra, said winning made her feel "really accepted".
"Because I get my boobs out for a living people think I'm tacky, an airhead and I'll have no personality. I think people can see past that," she said.
Sophie denied she had sex with fellow housemate Kris Donnelly while in the house although the pair were seen sharing a bed. "I can swear on my Chihuahuas's lives I never," she said.
Sophie spent much of her time in the house as Dogface after changing her name by deed poll in a task which gave her housemate status.
The model, who lives with her parents and two older brothers, lived up to the name when she got on all fours and impersonated her pet Chihuahuas, Army and Moo.
