Katy Perry wants to raise the standards for her forthcoming tour by ensuring it smells good.
The California Gurls pop star will bring her California Dreams show to the UK, and is insisting on a 'scented' 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."
Katy has been working with Pink's touring director to get some top tips on how to put on a show.
"I just really want to raise the bar," she said.
"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's UK leg of the world tour opens at London's Hammersmith Apollo on March 17 before stopping off at Manchester, Liverpool, Nottingham and Bournemouth.
