Katy Perry has revealed that she is excited about the use of 'smell-o-vision' during her California Dreams tour.
The singer told Rolling Stone:'It's the first concert that's going to smell good. It's going to smell like you're in cotton candy heaven.
'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.'
In the same interview, Katy said that she wasn't planning on only singing about her marriage to Russell Brand in the future.
'There is an obvious element in me that wants to entertain people and make their faces light up,' she said. 'So I won't only be singing songs about being a married woman. I always say a good example of that is Beyonce. She sang 'Single Ladies' but everyone knows she's with Jay-Z.'
The tour begins in Portual on February 20th.
