Paris Hilton has ended her romance with Good Charlotte rocker Benji Madden, according to U.S. reports.

Rumours suggesting the nine month relationship has ended began when the heiress was snapped cosying up to ex-boyfriend Stavros Niarchos in a Miami, Florida nightclub at the weekend.

And Hilton dumped her rock star beau just days later, friends tell Star magazine.

A source tells the magazine, "Paris was fed up with Benji always telling her what to do and bossing her around. She felt she couldn't cut loose and party. He doesn't drink and doesn't think she should either. She felt too fenced in."

The insider adds, "She couldn't take his overbearing ways anymore. It was stressing her out. He can be very aggressive and he was just too much trouble.

"He fought for a second chance and asked if they could talk it out but Paris said she was done talking."
