Somehow we can't ever see Kelly Brook popping on a saftey helmet and lycra cycling shorts for a ride round the park (just imagine the helmet hair), which might explain why she's chosen to front the Sky Ride campaign every year.
Kelly threw caution to the wind again this year and opted for the very impractical combination of wedge heels and a summery mini dress (Topshop if you must know) for a peddle round London's Regents Park.
The three year old Sky Ride campaign aims to inspire millions of people to get on their bikes and excited about cycling with organised bike rides around the country.
Meanwhile, Kelly has spoken about the indecent proposal she received at this year's Cannes Film Festival and insists she was actually flattered by the offer of £800,000 that a stranger offered her in return for a night of passion.
A man, known only as Frederic, approached the star on the red carpet where she was promoting Keith Lemon: The Film.
Hec reportedly begged Kelly to sleep with him before he was ejected from a photocall at the lavish Majestic Barriere hotel by a bodyguard.
After originally assuming it was a prank arranged by funnyman Keith, Kelly eventually attempted to find the man to thank him for what she deemed a compliment.
During a chat on Lorraine on Tuesday, she said: "It was flattering. I tried to find him afterwards. I was like, 'I'm doing a photocall, give me five minutes.' But no, I think it was just a joke. Cannes is full of people doing silly things and having pranks."
