A Coty, Inc. exec says snowballing celebrity scents all started with the launch of Glow by J.Lo in 2002, which sold $78 million before 2003. Now celebrities (Avril Lavigne, Queen Latifah, Patrick Dempsey, Mariah Carey...) see fragrances as a way to solidify a strong career as more and more people buy their scents to smell like them.

As much as we all love Jenny from the block, we don't love Avril or Mariah, and don't want to smell like either one of them. Sick of going to Sephora for a new fragrance, and all the sales girls suggest one another celeb scent that recently launched.
