I agree!! Some celeb fragrances are pretty awesome! I have not tried Heiress but I heard a lot of good comments !! Some other great celeb fragrances are Rihanna Reb'l Fleur, JLO Miami Glow, Kim Kardashian (the original) and I could name quite a few more :) (y) :D
I know there is a bit of snobbery about celeb fragrances/Paris Hilton but I've tried a few of hers and they're great. Particularly like Heiress (I have the stronger, limited edition diamante bottle), Tease and Fairy Dust. I'd say Heiress is my favourite. My niece used to wear Can-Can and the original Paris Hilton fragrance, liked those too.
