Glamour model Sophie Reade, who changed her name to Dogface to compete in the reality show, has won Big Brother 10.
The 20-year-old from Nantwich, Cheshire, saw off competition from "slave to fashion" Siavash Sabbaghpour, 23, to win the prize fund of £71,320.
Earlier, the public voted David Ramsden third, Charlie Drummond fourth and Rodrigo Lopes fifth.
Sophie, who won 74.4% of the final vote, said: "I never thought I would win...I can't believe it."
She 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.
She added she planned to spend her prize money on clothes and give some away to charity.
The remainder of the £100,000 prize fund, which had been taken away after the housemates tried to break out, will go to charity Channel 4 said.
