LONDON - LEWIS Hamilton may be the hottest property in Formula One, but Miss Grenada had no qualms dumping him for two-timing her.

Vivian Burkhardt also revealed the lonely life of the 23-year-old McLaren driver.

'His life away from the track is far from glamorous,' she told the News of the World.

'Despite his huge wealth, I hate his lifestyle and feel sorry for him.

'There he is in Switzerland, where he has no friends, no family, just this amazing four-bedroom flat in the richest part of the city - but it's simply big and empty.

'He just spends his spare time playing Formula One PlayStation games over the Internet with his 15-year-old brother Nic in England.

'The rest of the time, he's texting friends who are miles away all over the world.

'Lewis told me how hard it was living in Geneva all alone. He said there's nothing to do and he doesn't know anyone. I know he's bored and unhappy and would like to move.

'But he stays because it's the one place he's not constantly recognised or approached. And, of course, it's a tax haven that's saving him millions.

'But how cheap is that, to not live with your family just to get out of paying tax?'

Burkhardt is bitter about the way Hamilton courted her, and then started dating Pussycat Dolls singer Nicole Scherzinger, 29.

Burkhardt and Hamilton had met in Grenada, home of his grandfather, in February, when the driver was being honoured at an awards ceremony.

In May, he flew the 22-year-old by private jet to the Cannes Film Festival for the premiere of the latest Indiana Jones movie.

'After we were pictured arm-in-arm at Cannes, suddenly the whole world knew me as Lewis' girlfriend. My mum was convinced he was the one and had dreams of us getting married.

'But days later, he was pictured cosying up to Nicole in Monaco. I was very disappointed. I thought he could have shown me a little more respect.

'Maybe he thought he really liked me a lot - before I refused to have sex with him. And then he changed his mind.'

The latest tabloid revelations completed a bad week for Hamilton, who finished out of the points at the French Grand Prix on June 22.

On Saturday, he was also involved in a crash before the start of one of the world's largest yacht races, although he was not to blame.

Hamilton was aboard the Open 60 Hugo Boss with Olympic medallist Ben Ainslie and round-the-world yachtsman Alex Thomson on the Round the Island Race off the Isle of Wight. Their yacht collided with another yacht, the Farr 45 Atomic, which was dismasted.

The bowsprit of the Open 60 Hugo Boss was damaged but it was able to finish the race before being disqualified.
