Kate Moss has prompted speculation that her relationship with Jamie Hince may already be over after she was spotted cavorting with another man over the weekend.

Kate was spotted sunbathing topless in Mexico during time out of a Topshop photo shoot over the weekend, with the mystery man close by. The pair were seen laughing together then at one point he lay on top of her on the sun-lounger.

The News of the World published pictures of the incident yesterday and an onlooker reported: “They were very playful and touchy-feely and seemed to be having a lot of fun.”

Kate and the Kills guitarist Jamie got together over the summer but Kate is said to find him too nice and not exciting enough as a boyfriend.

A source claiming to be a friend of the supermodel added: “Jamie is very quiet and prefers walks in the country to beach fun.”

“Kate is over Pete but she misses the mayhem that went with him.”
