British newspaper the News of the World, yesterday published claims that Moss becomes wildly sexual during cocaine-fuelled parties, and has orchestrated a number of lesbian romps with friends including Frost and British TV star Davinia Taylor.
Rebecca White, a fashion PA who claims to have known Moss since 1998, tells British newspaper the News of the World, "She is naturally a very sexually open person. But, when she's doing cocaine, she becomes even more so and will fall into bed with whoever she chooses. Women as well as men."
Another source tells the tabloid, "Kate was high and the other two (Frost and Taylor) were drunk at a bash. They went up to a suite and got in bed together. They were watching television together when Kate started chatting about sex.
"She had already been to bed with Sadie--so she asked Davinia if she had ever done it before. They started snuggling and soon they were having a threesome with Sadie."
The claims come just days after another British newspaper published pictures of Moss purportedly snorting cocaine.

Moss has been accused of trying to seduce a personal assistant (PA) while under the influence of cocaine.

White says, "I was working with Anna Friel at a fashion event in New York. Kate was there--and high.
"She told me that she head to go back to the hotel to change her clothes. She said, 'And you're coming with me.'
"When we got back to the hotel room, Kate immediately tore off her black dress. She came up to me in her panties and started kissing me.
"We fell onto the bed together and she touched my breasts, but after a few minutes of groping and kissing, I started to feel nervous and pushed her away."
Moss Made Joint out of Tampon Cover
Moss is reportedly such a seasoned drug user she can make a cannabis joint using a tampon cover.
Former Babyshambles manager James Mullord was stunned when the supermodel shared her sordid trick with him--especially as he had hoped she would be a calming influence on her boyfriend Pete Doherty.
He says, "She once showed us how to make a joint out of a tampon cover which was pretty impressive. She knows a lot about drugs.
"I've never seen Kate completely out of it on drugs. Though she gets a bit melodramatic and stroppy when she's had a bit."
Moss Apologizes to Fashion Bosses
Moss has made a sincere apology to high street fashion house H&M after a British newspaper published photographs on Thursday of the supermodel allegedly snorting cocaine.
The UK beauty recently secured a $1.8 deal to advertise a new range of H&M clothing designed by Stella McCartney--and the Swedish company expressed disappointment with her behavior during a face-to-face meeting in New York City.
But fears Moss would lose a series of lucrative contracts seem to have been allayed with the news that H&M marketing director Jorgen Andersson has accepted her apology and will go ahead with the advertising campaign fronted by the 31-year-old.
H&M spokesperson Anacarin Bjorne says, "We are very anti-drugs and insist all our models are healthy and sound. What happened is in Kate's private life, but we are all very disappointed in her.
"Kate has apologized and was full of remorse for her actions. She has assured us it will not happen again, and we are willing to give her another chance."
Moss earns an estimated yearly income of $7.2 million from a series of longstanding contracts other fashion houses including Burberry, Christian Dior, Rimmel, H. Stern and Chanel--and representatives for most her employers have refused to comment on the scandal.
