Kate Moss has fuelled rumours after she was seen looking at engagement rings with lover Pete Doherty.

The supermodel and the former drug addict were browsing over sparkling bands during a romantic trip to Florence at the weekend.

One onlooker said: "They both looked like a pair of loved-up teenagers but they were taking the matter of rings very seriously. There is no guarantee it's an engagement ring but it seems significant to them."

Kate, 32, made her best efforts to hide the sparkler when she arrived in Heathrow airport yesterday (10.22.06), by covering it up with her sleeve.

Meanwhile, Pete's uncle Phil Michels has claimed the 32-year-old catwalk queen is pregnant with his nephew's baby.

He told Britain's Sunday Mirror newspaper: "I have spoken to Pete twice about the baby and he has confirmed that Kate is pregnant. They are both delighted and Pete sounded really excited. Pete told me they want a baby to cement their marriage."

Meanwhile Kate has reportedly given Pete a list of six rules which he must obey or she will call off their alleged wedding.
