Hundreds of excitable teenagers waited eagerly for pop star Katy Perry until she drove up riding pillion to the launch of her new fragrance 'Killer Queen' in Berlin on September 25.
The excitement reached fever pitch when she finally dismounted, which even seemed to take the singer by surprise.
The perfume is described as being "charmingly playful yet lethally gorgeous" but the cartoon-like singer added a more vivid description at the launch.
(SOUNDBITE) Pop singer, Katy Perry (English), saying:
"It feels very luxurious, I have my own crest on the very top and the scent is very sophisticated, but not too much, like it doesn't spell like Grandma, but it's not forgettable as well so it's just perfect."
Perry is known for her eccentric quirky fashion and fans turning out for the signing did their best to emulate her styles - some more than others.
(SOUNDBITE) Unidentified fan of Katy Perry (German), saying:
"She's a strong personality and she can laugh about herself and be funny. She's very creative and just a 'wonderwoman'."
This isn't Katy Perry's only launch this month. Her album 'Prism' is due out in mid-October.
