Formula One champion frontrunner Jenson Button has slapped a sex ban on himself in the hope of snaring the much coveted title in Brazil.
The Brit needs a third-place finish in Sunday's Brazilian Grand Prix to win the F1 Championship and has left gorgeous model girlfriend Jessica Michibata at home.
Only a few weeks ago, the Brawn star revealed the secret of his success was her foot massages.
A source close to Brawn GP said, "It's such an important weekend for Jenson. He has hundreds of things to do and wants to be able to concentrate on them alone. Jessica normally always travels with him but he has to keep his mind on the job - so to speak."
