Well Rihanna did it on Facebook with her last album and now Katy Perry is doing it with her latest fragrance. Starting next week on Twitter, Katy will be inviting her fans to guess what it's called.  The winners will be chosen at random to win prizes like bottle of perfume, or a pass to a meet-and-greet with Katy during a launch event in December.  After the success of her first fragrance, Purr, Katy Perry is ready for a second round.  Katy's second scent will launch this November exclusively at Nordstrom and Nordstrom.com.  The scent, which Katy created during her California Dreams tour, is designed to be a "companion piece" to Purr.   My guess is Meow...so you can steal that if you want to enter!
