The twins celebrate a booze-free birthday

The contestants had to create their own fun after Big Brother steadfastly refused to provide any music, alcohol or cake for yesterday's festivities.

First the blonde twins sang Jingle Bell Rock while the others tried to line dance. Then they played musical chairs and musical statues before starting an "adult" game of Chinese whispers. Meanwhile, Model Billi, youth health worker Carole and raver Tracey are facing eviction from the Big Brother house this week.

Two-faced Charley, 21, escaped yet again, despite her own vote being discounted as punishment for discussing nominations.

Billi, 25, from Middlesex, received seven nominations, while Tracey, 37, and Carole, 53, received four each. Bookies make Billi, a newcomer to the house whose votes were also discounted for discussing the nominations, favourite to get the boot on Friday.

Billi was nominated by Brian, Chanelle, Liam, Nicky, Sam, Tracey and Ziggy. Essex boy Brian said of Billi: "I don't completely 100% trust him. I told him that I fancy someone in this house and the next minute he's all over them."

He went on: "He always talks about what being in this house could do for his profile or modelling career. I just think he'll tread on anyone in
this house, including myself, to get what he wants at the end of it."

Posh Spice fan Chanelle also nominated Billi, who fancies her, saying: "He has caused a big thing between me and Zac, 'cos Billi started mentioning stuff like how we were gonna be in a love triangle."

Chanelle added: "He stares at me and Zac whenever we are kissing. I don't think that's a normal thing to do." Tracey was nominated by Amanda, Jonathan, Liam and Gerry.

Carole got votes from Nicky, Tracey, Sam and Laura. Amanda nominated Tracey, saying: "She's getting more wound up than most other housemates... she acts more stressed."

She said she did not like Tracey telling her off at night for having fun, adding: "You're in the Big Brother house, you obviously knew that's what you're in for."

Self-made millionaire Jonathan also nominated Tracey for the second time, saying: "I think she comes from planet Pluto and I find her quite irritating.

"I don't like talking to people who just speak in jargon or slogans." He continued, "She's like 'I'm a rebel/teenager' who's really one of the thought police."

Liam nominated Tracey, saying her phrases were annoying him and she could not have a proper conversation, and also selected Billi because "he is very calculating, he's coming across as quite sneaky".

Nicky nominated Billi, saying: "He's made people feel uncomfortable and I don't like it... ugh." She added: "He's been making suggestions towards Sam and she doesn't like it."

She also nominated Carole, saying: "She makes me feel awkward sometimes. I don't really have a relationship with her." Tracey nominated Carole, saying she was "snappy over minor things" and Billi because "he's got a game plan".

Ziggy nominated Billi because "he's played some games, he's trying to play people off each other".
He added that Billi circled Chanelle whenever he left her side. He also nominated Charley for a second time, saying: "She's quite sly, she likes to play people off each other. I just don't trust her."
