Sadly for her fans she's just teasing - with a group of football stars instead doing the hard work.
Instead of joining in Kate simply walks up to the vehicle, points at the bonnet and states: 'You've missed a spot.'

As the football stars look on open mouthed she then strolls off, her legs on show in denim hotpants.

As an underwear model they might have been hoping the 20-year-old would show a little more flesh.
Model Kate came to prominence when a YouTube video of her doing the Dougie at a Los Angeles Clippers game went viral in 2011.
She has since made the jump from swimwear to high fashion, fronting the January edition of British Vogue.

Kate has starred in Super Bowl spots in the past, including one for Carl’s Jr. during last year’s game.
