New York, October 07 (ANI): Kate Moss and rocker boyfriend Jamie Hince recently quarrelled at Simon Cowell's birthday party after a man in a banana hammock thong grabbed her.

"The man was singing Journey's 'Don't Stop Believing' and stripped down to a thong. He waded into the crowd and grabbed Kate, picked her up and started twirling her around," the New York post quoted a source as saying.

"But as soon as he put her down, Jamie stormed over and began shouting at her," the source added.

However, party organizer Lady Tina Green calmed things down, and the couple patched up before leaving together at 4 a.m.

All celebrities present in the party including included Ryan Seacrest, Randy Jackson, and Naomi Campbell apart from reps for Moss and Cowell have all maintained silence over the issue. (ANI)
