Rebecca White worked for the British catwalk star for three years from 2001, and claims she witnessed the extent of the tragic actor's drug addiction several times during her employment.

She tells British newspaper The Sun, "When I was working for Naomi I saw Heath do drugs a few times. He was new on the scene but everybody was hailing him as the new It Boy actor. "We had been hanging in Naomi's bungalow at the Bel Air Hotel. Heath asked Naomi if she had any cocaine - I use to carry it around for her - and I remember giving him the packet and he went off, back and forth throughout the night."

At another celebrity event, White claims to have seen Ledger take ecstasy with reformed addict Campbell: "We went to… (a) party at this club. There was coke and a big bag of ecstasy pills. Naomi gave Heath a handful of these little blue pills and I remember him putting them all in his mouth at once and swigging a bottle of Cristal champagne."
