Sam walks out of the Big Brother House Oxford student Sam Heuston will have to find something else to do for the next couple of months after her turbulent three-week stint on reality TV show Big Brother ended upbruptly with her eviction on Friday night.

Sam, 23, a marketing student at Oxford Brookes University, has been involved in heated rows on the Channel 4 show and hit the headlines after snogging female housemate Makosi.

The Oxford party animal -- who was sacked from a job at the Park End night club for drinking too much -- was one of three housemates up for eviction and smiled as her departure from the house was announced by host Davina McCall.

Former boss Zoltan Branch, manager of the Park End club, said he was left with no choice but to dismiss Sam, who comes from Surrey, from her promotions job because of her wild drinking and partying habits.

Sam, who shares a house with friends in east Oxford, worked at the club from September 2003 until June last year as a "spank girl", promoting the venue's Monday student night by luring customers from other bars.

She was tasked with bringing in students until midnight and was then allowed to continue partying in the club.

Mr Branch would give his employees five free drinks vouchers to enjoy, which he says lasted all night for everyone except Sam, who would come knocking on his door to ask for more after just 30 minutes.

Sam was also a dancer at Fuzzy Ducks, the former student night at The Zodiac, and is also a regular at the City Arms pub in Cowley Road.

Bookies William Hill said Sam's eviction had left them out of pocket. Spokesman Rupert Adams said: "We have not counted the shop bets yet, and already we have liabilities of over £20,000. "This is without doubt the biggest caning we have ever taken on reality TV."

Sam was the hottest 1/14 favourite that the Big Brother betting had ever seen, he added.

"In the last three days we shortened Sam's price at least 15 times," he said.

"I certainly cannot explain why anyone would risk £14 to win £1 but that's what they were doing."

Sam left the house smiling and waving to be greeted by a glamorous Davina McCall wearing a shimmery long black coat.

Not to be outdone by the scantily clad contestant, Davina whipped off her coat to reveal a black bikini to cheers from the crowd.

The embarrassed-looking television presenter was then treated to a lapdance from Sam after she mocked her earlier efforts at dancing for fellow housemate Anthony.

After leaving the house, Sam said she had bonded with Makosi and admitted she had blossomed after busty rival Lesley left the house. She said the two "just didn't get on".

And she had few kind words for the rest of the house, describing Roberto as "annoying" and Saskia as "not my kind of girl".

Sam's parents have since admitted they were "gobsmacked" to see her misbehaving on screen, particularly as they watched her kissing another girl, but said the family was "fairly broad-minded".

She had warned her parents she was going to prance around in tiny bikinis on the show and tell everyone she was a lap-dancing bisexual.

Fellow contestants Derek and Roberto had also been nominated for eviction. There are now 10 housemates left.
