WWW- Are fashion and cosmetics companies starting to find waifish Kate Moss too heavy a lift?

No sooner has Moss apologized to her modeling employers for using cocaine than fresh gusts of scandal are buffeting the mannequin.

Over the weekend, sources claimed in Britain’s News of the World that Moss had lesbian romps with actresses Sadie Frost and Davinia Taylor, as well as a three-way with Frost and her former husband Jude Law.

Fashion p.a. Rebecca White was quoted as alleging that she’d seen Moss and pal Naomi Campbell blow their way through a “fist-sized” mound of cocaine in a single night.

White also told the paper that Moss “asked for several hundred [British] pounds’ worth of cocaine” before attending a 2002 benefit for Nelson Mandela Children’s Fund.

“She sneaked off to [take cocaine] all the way through the dinner, with Nelson Mandela at the next table,” said White. “I couldn’t believe how disrespectful that was.”

Christian Dior, Burberry and H. Stern have all sidestepped any definitive answer on whether Moss will stay with them.

A rep for retailer H&M said Friday that it wouldn’t dump Moss because she had apologized for her drug use and promised in writing to remain “healthy, wholesome and sound.”

But yesterday, H&M seemed to be distancing itself, with a rep saying: “We are having a dialogue with her. This is a very unfortunate situation.”

Meanwhile, London’s Mirror reported that Moss has split with boyfriend Pete Doherty. The bleary-eyed rocker was seen a disco on the Spanish isle of Ibiza without Moss – instead kissing another man.

Moss’ rep would only say yesterday that “all these allegations are being dealt with by lawyers, and we will not be commenting at present.” A rep for Campbell, who in the past has been open with the press about her cocaine use, declined to comment.
