Pussycat Dolls star Nicole Scherzinger is dating Formula One racing driver Lewis Hamilton.Despite denying she was romancing the sports ace, she has now reportedly told friends they are an item.Speaking after this weekend's Monaco Grand Prix - which Lewis won - Nicole said: "We've been seeing each other on and off for three months. He was amazing today."Nicole missed the launch party for the new Pussycat Dolls single 'When I Grow Up' because she was in Monaco as a special guest of the British driver - where she was introduced to Lewis' family.A source revealed to Britain's Daily Mirror newspaper: "Lewis and Nicole spent time with his family to celebrate, then snuck off to the Amber lounge."Lewis only had eyes for Nicole - he couldn't keep his hands off her. They were kissing as if no one else was watching."Then Lewis pulled Nicole up on stage and DJ-ed hip-hop tracks. It was packed with celebrities including Jenson Button. They went wild when they saw him with Nicole."

Nicole and Lewis first met at the MTV Europe Music Awards in Munich, Germany, last November.
