London, Nov 2 : Lewis Hamilton's singer girlfriend Nicole Scherzinger has reportedly promised him a bonus prize of a week of lust in Las Vegas if he wins his first Formula One world championship in Brazil.

Britain's F1 golden boy will get to enjoy the hottest seven days of his life in Nevada with Scherzinger.

However, he's got to scorch past the chequered flag in Interlagos to land the championship before he can claim his super sexy treat.

"Nicole has promised him that, if he wins, she'll pamper him for a whole week in Vegas," the Daily Star quoted a pal, as saying.

"She says she will be his to command and she'll cater to his every whim and desire. What guy wouldn't burn up the track after an offer like that?" the pal added.
