Moss hogged the limelight at the Hoping Foundation charity bash-held at Jemima Khan's Kiddington Hall in Oxfordshire-where she auctioned herself off for more than 10,000 pounds to play tambourine onstage with her boyfriend, Kills guitarist Jamie Hince, and Nick Cage.
Fellow celebs, including Tom Jones and Guy Ritchie, looked with amazement as Moss chucked away the broken tambourine and started sexy dancing with Nick Cave's wife Susie Bick instead.
"It had been a sombre evening hearing tales about Palestine - until Kate turned up. She was creating havoc and loved going wild on stage with Jamie and Nick," the Mirror quoted one party-goer as saying.She thought it was hysterical when she broke the tambourine. Still, at least the auctioneer put it to good use and raised 5,000 pounds for charity for it from a generous bidder," added the source.
Giggling mischievously, the actress jumped off the stage and grabbed Tom Jones in a bear hug.
She did a little dance for him before demanding he perform 'Sex Bomb', saying: "Go on Tom, it's your turn next."
But Tom replied: "You can bid for me to sing anything, but I'm not singing that."
Instead he did 'Green Green Grass of Home' with Nick Cave. (ANI)
