What to expect from Katy Perry's world tour
Katy Perry has promised "spontaneous crowd interaction" during her tour.
The 29-year-old popstar is kicking off her Prismatic World Tour in May next year in Belfast, Northern Ireland.
Giving fans a hint of what can be expected from her third stint on the road, Katy described just one of the theatrical plans she has up her sleeve.
"You should see the stage that I've built for this tour - it is so exciting. It's literally in the audience. I can be as close or as far as I want," she gushed to BBC Radio 1 DJ Nick Grimshaw.
"[Touring is] a little bit harder than you think but it's overall very satisfying and exciting... for the tour I've begun to develop this idea of spontaneous crowd interaction, bringing people on the stage. Which is exciting because I think I have a good intuition so if one of them has crazy eyes I'll leave them off."
Katy continued to reveal what she loves to do while staying in the UK.
During her visits to London the raven-haired beauty admitted there is one thing she always makes time for.
"I like to soak in the tradition and the culture that is the great England. I like to have high tea, which we don't even have [in American]. We have happy hour, but I think you guys have that too. I think you guys are always doing something concerning food, like high tea or breakfast or lunch or happy hour," she laughed.
"I have had tea at Claridge's [hotel] which was really nice. I try and do it every single time. I love those sandwiches that have no crusts on them, and they're so fancy. But when I grew up and went to school, you could always tell who the rich kids were - the kids who the moms took all the crusts off. I had crusts!"
When performing Katy maintains a healthy diet. She credits her physical fitness to her mother Mary, who encouraged her to eat well from a young age.
"My mom's a health nut, but I think I feel very clear and healthy because of it. My mom always pumped vitamins into me, she always has from day one, and all kinds of juices and blends and stuff like that. I mean when you're on tour [I have to be] especially [healthy] yes," she added.
