Robbie Williams has a new girlfriend - Lisa D'Amato.

The American model has been regularly dated by the superstar singer since they met at trendy Hollywood club Social last month.

Friends say Robbie, 32, is truly smitten by the 25-year-old beauty.

A source close to the star said: "Robbie and Lisa hit it off immediately and swapped numbers the first night they met.

"Lisa is young, gorgeous and fun to be around and they are getting on really well. It's only early days but Robbie seems really confident it is going somewhere." Robbie has invited Lisa to his Beverly Hills mansion several times. Our source added: "It takes a lot for Robbie to trust a girl, but he is completely relaxed around Lisa.

"She has been spending quite a lot of time at his place, which proves just how keen he is."
