Hamilton denies engagement rumours

Lewis Hamilton has denied reports that he is engaged to Pussycat Doll Nicole Scherzinger.

The Formula One champion's girlfriend was seen wearing a ring on her engagement finger earlier this week, but Hamilton insisted that they have no plans to marry just yet.

He said: "I'm very happy. We're both very happy. I definitely sleep with a big smile on my face.

"I'm very fortunate not just to have success but I do have the most beautiful woman by my side."

An audience of 13.1 million saw Hamilton take the world title in Sunday's Brazilian Grand Prix.
