Spilling cleavage and micro mini skirts galore as Big Brother has-beens grasp for attention

Former Miss Wales Imogen Thomas, who made a rather unmemorable appearance on the reality show in 2006, wore a black top with a neckline that wasn't so much plunging as non-existent in a desperate attempt to grab the spotlight.

The 23-year-old was spotted leaving Movida nightclub in London's Soho with Nery Castillo, the Mexican footballer who has just joined Manchester City.

Her efforts were matched by Chanelle and Chantelle, who both opted for micro mini skirts as they arrived at The Collection club across town.

They both turned out for the Miss Great Britain reunion party - despite the fact neither have ever entered the competition.

No doubt the siren call of free champagne - and inevitable presence of photographers - was enough to get them slipping on their tiny frocks.

The onetime Posh lookalike and apparent optimist Chanelle is still holding out hope of using her appearance on the show last year to launch a successful pop career.

Talking about her forthcoming debut single, she has said: "The song actually sounds a bit like recent Britney.

"To be able to go on iTunes and download my own song is a massive achievement for me. But I'm taking it slowly."

She continued: "I've been putting everything into my music. I've been working 15-hour days and then going home and playing with my gorgeous Pomeranian pup Crumpet and going to bed.

"I've even had to put my plans for a boob job on hold because I can't afford to take three weeks off."

Chantelle, who won Celebrity Big Brother in 2006, had no such trouble clearing her schedule.

She had her bust boosted to Jordan-esque proportions after splitting from her husband, Ordinary Boys frontman Preston, last year.
