Paris Hilton "went totally crazy" exercising before her recent raunchy photoshoot.

The hotel heiress - who is seen wearing a tiny boob-tube bikini top and short skirt in the advertising campaign for her new fragrance Fairy Dust - was reportedly thrown into a panic when she found out what bosses had chosen for her to wear in the shoot.

A source close to Paris told Fox News: "Paris didn't want to be airbrushed so as soon as she found out what she had to wear she went overboard with Pilates classes and exercise - she went totally crazy toning up."

The 27-year-old beauty also came up with the idea for the shoot - which shows her waving a magic wand and wearing fairy wings complete with the tagline, 'Do you believe in fairy tales?' - because she wanted to "bring some fantasy to her fans during these tough economic times".

A shoot insider said: "Paris wanted to look ethereal, but also wanted her perfume to inspire people. She hopes she has done that with the new campaign."
