The Grammy winning singer who like Moss has a long history of drug addiction were at a private party being attended by Hollywood A-listers, when Winehouse pocketed the drug stashed away in the supermodel's handbag, reported Daily Mail online.

"Kate had told Amy to get a USD 10 note out of her handbag to snort lines with. But Amy told me she found two grammes of cocaine in there, so she nicked them. We did some in the toilets but we did the rest in front of everyone," said Fielder Civil who has reportedly been sent back to rehab after failing another drugs test.

The former jail-bird who divorced Winehouse 11 days ago alleging infidelity had reportedly asked for USD 6 million pounds as part of the divorce settlement.
