British Grand Prix winner Lewis Hamilton's burgeoning romance with Pussycat Doll Nicole Scherzinger is continuing at lightning speed as the couple stepped out together at a racing event yesterday.

Despite a brief return to her native America to celebrate her 30th birthday in Las Vegas two weeks ago, Scherzinger rushed back to Europe to be with Hamilton following his Grand Prix win at Silverstone.

The pop star joined Hamilton, 23, at the Goodwood Festival of Speed in West Sussex, where the racing ace showed off his driving skills on the hill climb circuit.

The couple were joined at the event by Billy Connolly, Chris Evans, Bryan Ferry and his girlfriend Katie Turner.

Despite being first linked last November after they were spotted getting cosy at the MTV Music Video Awards in Munich, Germany, Hamilton went on to start dating Miss Grenada Vivian Burkhardt.

Just days after parading Burkhardt at premieres and parties at the Cannes Film Festival in May, Hamilton did an apparent U-turn and switched his attentions to the Pussycat Dolls frontwoman, who joined the driver at the Monaco Grand Prix.

A devastated Burkhardt, who flew back to Grenada following her trip to Cannes, told the News Of The World: 'After we were pictured arm in arm at Cannes, suddenly the whole world knew me as Lewis’s girlfriend.

'But days after Lewis got into bed with me, he was pictured cosying up to Nicole in Monaco. I was very disappointed. I thought he could have shown me a little more respect.

'It looked like he was playing me. And I felt the world was laughing at me. He called me soon after and has been in touch almost every day since but I don’t even want to talk to him about it.'

In May, Scherzinger was reported to have told friends they had been dating 'on and off for three months'.

Last month, they arrived together at Nelson Mandela's 90th birthday bash in London's Hyde Park, where they mingled with A-list stars including Bill Clinton, Oprah Winfrey, Uma Thurman and Sir Elton John.

Things are going so well with Scherzinger, Hamilton has already introduced her to his father Anthony, stepmother Linda and half-brother Nicholas.
