Katy Perry launches new perfume 'Killer Queen' with new ad

Katy Perry has launched her third perfume 'Killer Queen,' which is being sold in a sceptre-shaped bottle in a royal shade of red.

The supposedly regal scent, priced from 23.50 pounds, is marketed as "lethally gorgeous" with Perry herself parading about in ermine in the opulent promo video, Contactmusic reported.

Using the slogan "Own The Throne," the ad shows Katy as an 18th century Queen, clad in powdered wig and being dressed in corsetry and framed skirts by bustling servants.

After becoming exasperated with all the attention and tight undergarments, Queen Katy whips out a knife, cuts off her skirts and lets lose her hair before storming the throne room.
