* 3.4 oz. (100 ML) eau de parfum spray * new in tester box * with outer cap * 100% authentic Pop star Katy Perry launches her third fragrance and the first one done in cooperation with Coty. The scent is called Killer Queen by the song written by Freddie Mercury, and apparently it is totally different from its two predecessors. Killer Queen has been in my vocabulary since I was 15, because of the song Killer Queen by Queen, said Perry to wwd. Freddie Mercury painted the lyrics of this woman who I wanted to be. She seemed very powerful, and she captivated a room when she walked in. I named my company Killer Queen after those lyrics. I feel like, after all this time, it was appropriate to use that name in association with something I did. I feel like Im falling, finally, into that woman Freddie painted.
