'Teenage Dream' sensation Katy Perry has spoken out about her forthcoming new fragrance, 'Killer Queen'.

She dramatically unveiled the perfume back in May with a royal-themed party and has now explained to Women's Wear Daily that getting the scent right was a real labour of love:

"It took us something like 30 or 35 tries to get it right. I wanted some floral [notes], like jasmine, but I also wanted red velvet flower, which is incredible — it gives it the edge that makes it Killer Queen."

"It’s for someone sophisticated, who wants a little edge and can wear it all day, and still wants that sexiness."

Perry added that she wants to perfume to stand alone and not be seen as a celebrity project because she believes the fragrance is good enough to transcend the connotations of her name and do well in the cosmetics industry without the superstar link:

"I just hope to put out a real quality project that competes, and competes beyond the celebrity fragrances. We’re making a product that really stands out on its own, beyond my name.”
