Katy Perry - Katy Perry Planning 2011 Tour Aroma
Katy Perry has big plans for her 2011 tour, including an ''aroma'' to excite the noses of her fans.
Katy Perry is creating an "aroma" especially for her 2011 European tour.
The 'Teenage Dream' singer is planning a spectacular stage show for her tour next year and is determined for it to engage all the senses of her audience.
She said: "It's going to be great - all the dates have sold out in the UK already. I want it to be really fun and very visual.
"It's going to engage all the senses, so we're looking into alternative stuff like smell. We're talking to a couple of companies at the moment about creating an aroma for the performance."
Katy, 26, also promises the tour will see her appear in several of her signature outrageous outfits on stage.
However, she admits it's not particularly easy to get in and out of the clothes between songs.
She explained: "There will be a medley of looks, and they'll be very strong. When I get changed during a show it's like I'm at a Formula One pit stop. There's Velcro being ripped off and stuff getting strapped onto me.
"On my 'Hurricane' tour I wore a different outfit every single night. It was crazy, and not cheap."
Katy's European tour starts in Lisbon, Portugal, on February 20 and runs until April.
