Lewis Hamilton hunts Doll house

SPEED king LEWIS HAMILTON is always quick off the mark-and now he's in a race to find a place with lover NICOLE SCHERZINGER.

The Formula 1 leader and the Pussycat Doll are looking to buy a luxury lovenest in London.

I'm told Lewis - racing in the European Grand Prix in Valencia, Spain, today - is now virtually joined at the hip with gorgeous Nicole.

A source on the circuit says: "Lewis and Nicole are getting pretty serious. They're almost living in each other's pockets as it is, but we're hearing that they may be about to buy a place together.

"It would only be a part-time base because Lewis is based in Switzerland."

London will be a handy place to meet up in between Nicole's American home and Lewis's Swiss tax haven.

The source added: "The fact they are planning to get a place shows how serious they've become."

Lewis, 23, keeps popping up at Pussycat Dolls promotional events all over the world.

RACY: Nicole's a doll

He had his luggage nicked the other week from outside the Spanish hotel where he was staying with Nicole, 29.

"It's surprising to get your luggage nicked from a place like that," said my source.

"But what's not a surprise is that Lewis was there with Nicole. Wherever she is you'll find him. They're like each other's shadows. The week before that they were in Hollywood together."

Lewis first met Nicole at last year's MTV awards but things really started hotting up after he won the Monaco Grand Prix in May. Since he split with long-term girlfriend Jodie Ma, who he had been with since they were at school together, Lewis has been linked to a string of beauties, including Natasha Bedingfield and Danielle Lloyd.

He was also pictured with Sara Ojjeh, 18, the daughter of millionaire Mansour Ojjeh, the man who part-owns Lewis's McClaren racing team and the team's sponsors Tag Heuer.

Lewis, who just missed out on winning the F1 championship in his first season last year, left Miss World runner- up Vivian Burkhardt broken- hearted when he ditched her for Nicole.
