The socialite is getting ready to launch her latest scent, Fairy Dust, and she wants to look her best.

She says, "I didn’t have to lose weight, but I just wanted to look really good. I started doing Pilates.�

And, as for the name of her fifth fragrance, Hilton says, "I just love Tinkerbell and fairies, so I thought it would be really fun.�

Hilton has a pet Chihuahua named Tinkerbell, and in 2004 authorised a book in the dog's honour, dubbed the The Tinkerbell Hilton Diaries: My Life Tailing Paris Hilton.
