Katy Perry's tour with 'pizazz'

Katy's promising bells and whistles and 15 costume changes on her California Dreams tour.

The Firework star also told Rolling Stone that fans will enjoy a 'sweet' gig.

"It's the first concert that's going to smell good - it's going to smell like you're in cotton candy heaven," she told Rolling Stone.

"It's a fun little nuance. I am a woman of detail, and you will be seeing that - even down to the 15 outfit changes I'm doing in concert."

"Touring is no longer an ordinary thing where you play an instrument in jeans and a T-shirt. It has some pizazz these days, and I'm definitely bringing the pizazz with a lot of bells and whistles. The show has a Broadway feel to it. It's got a storyline that's going to be very interesting - kind of loosely based on my life, but a cartoon version."

Katy is working with the director behind Pink's spectacular Funhouse productions. The first time we will see Katy in the UK is at London's Hammersmith Apollo on March 17.
