Slim stars get skinnier!

Nicky Hilton
Size: Four
Weight: 45 kilos

A yo-yo dieter, Nicky's weight has always fluctuated more than her sister Paris's, but new pics of the heiress show that she no longer has any curves left. Keen to be taken seriously as a designer, Nicky has been working flat out on her fashion line, Chick, as well as jetting between LA and Japan - where she sells a range of handbags. Nicky's dismissed concerns, saying, "There's no truth to any starvation, eating disorders, rumours. I think that the press has been printing pictures of me from unflattering angles."

Sarah Jessica Parker
Size: Two
Weight: 43 kilos

The stress of shooting the SATC movie seems to have taken its toll on SJP, whose already slight frame has been whittled away to rib-revealing proportions. And the 43-year-old has had to publicly put on a brave face since she was named one of the world's most unsexy women by men's magazine Maxim, claiming the attack was "brutal".

"Do I have big fake boobs, Botox and big lips? No," shot back a rattled SJP. "Am I really the unsexiest women in the world? It's so brutal in a way, so filled with rage and anger." And insiders say that continuing on-set rows with Kim Cattrall have all contributed to SJP's shocking weight loss.

Amy Winehouse
Size: Two
Weight: 42 Kilos

Far curvier at the start of her career, the 24-year-old's seen her life descend into chaos of cartoon-like proportions. Apparently still addicted to drugs, despite a stint in rehab, Amy's figure has shrunk over the past few months, as her incarcerated husband Blake's trial has drawn closer.

And as footage of her caught on video by Blake singing a racist song, and pictures of her surrounded by what looks like drugs paraphernalia emerge, we sure to see stress cause Amy's weight to plummet even further.

Cheryl Cole
Size: Zero
Weight: 41 kilos

The Girls Aloud star, who is still refusing to put her wedding ring back on following allegations that hubby Ashley cheated on her, revealed a shockingly skinny frame last week, and the 24-year-old has blamed the band's gruelling dance routines on her weight loss.

"She has always been tiny," insisted her rep. "Yes, she has lost weight and she's aware of it - but if you're dancing for two hours a night and sweating a lot, it's going to happen." However, sources say the band are battling to ‘out skinny' one another. "All the girls seem to be competing with each other to see who can eat the least," a source told the Mirror.

Nicola Roberts
Size: Four
Weight: 45 kilos

Cheryl's Girls Aloud bandmate has long battled her low self-esteem issues, which have recently led her to become startlingly skinny. And with 22-year-old Nicola splitting from her fiancé Carl Davis and the stress of the girl's current Tangled Up tour, the redhead has, say pals, been losing even more weight off her already slender frame.

"When you're away touring you're working really hard," insists Nic. But pals have pointed to Nicola's confidence crisis as being behind her intense dieting, and the singer herself recently admitted, "For years I felt like the ugly one in Girls Aloud... They all look perfect with lovely hair and amazing tanned bodies. I was the ugly one, the odd one out."

Christina Ricci
Size: Two
Weight: 43 Kilos

The former child star stepped out last week looking shockingly skinny again, after years of suffering from eating disorders. Having seemingly recovered from her past forays into anorexia and bulimia, Christina, who's been working non-stop promoting her new movie, Speed Racer, appeared super-skinny once again, with a tell-tale ‘lollipop head'.

"At one point I had a little anorexia phase," recalls the 28-year-old. "I find the less attention I pay to food, the healthier I am. Everyone's obsessed right now with carbohydrates in this country."
