Fragrances launched by Britney Spears and Paris Hilton have been battling for customers - and it appears Britney is the winner.
The 23-year-old pop star's scent "kicked Paris Hilton's butt," a source told the New York Post.
Last year Britney launched her scent, Curious, in a deal with Elizabeth Arden while Paris also signed a deal to launch her fragrance, Paris, with a company called Parlux.
Hilton is said to be "extremely upset" at the poor sales.
The 23-year-old hotel heiress' reality show The Simple Life begins on Fox TV in the US later this month. thanks britneysmind.com
