Of all the celeb scents that have been coming down the line, we've been most excited for Katy Perry's Purr. Well, it's finally here, and it doesn't disappoint. The scent combines top notes of peach, forbidden apple, gardenia and green bamboo, with the heart of jasmine, pink freesia and Bulgarian rose, plus the base of vanilla orchid, creamy sandalwood, white amber, coconut and musk. And it comes in a too-cute kitten bottle. Mmm, sounds purr-fect.
