Ulrika Jonsson declared the vote must have been rigged when she was crowned the shock winner of Celebrity Big Brother in 2009.
The Swedish TV presenter saw off stiff competition from broadcaster Terry Christian, rapper Coolio and late Austin Powers actor Verne Troyer in the series six final.
After her name was read out Davina turned to runner-up Christian and said: "It's a fix."
Ulrika 's stunning victory appeared to be unpopular with housemates too given the poor turnout for her official party.
Just five of Ulrika's co-stars turned out to celebrate with her at London's Sway nightclub.
Ulrika's triumph had also been surprise with bookies who overwhelmingly predicted US star Troyer would take the top prize.
"Oh my God, That's just bonkers. It's a fix," cried mum-of-four Ulrika as she spoke to host Davina McCall. She had been nominated every week by her fellow housemates but won with 57% of the vote.
The ex GMTV weather girl wept as she was finally released from the house in front of the baying crowd at Elstree.
"It was the weirdest experience of my entire life and I’ve had quite a weird life," Ulrika said of her 22 days on the reality show.
While she clearly impressed viewers, Ulrika had irritated housemates with her bossy attitude - which she said her then husband had warned her about before she took part.
"I agonised over whether or not to come on. My husband said you can’t bear being around people, it will be a challenge for you.
"My husband says I’m bossy all the time. I am. In my defence, I have to organise four children so things have to be like that," she claimed.
Ulrika was rumoured to have been a whopping £175,000 fee to appear in the house, making her the highest-paid star on the show.
