In an interview with Rolling Stone (via Huffington Post), she explains, "After this interview I'm going to have a nice healthy breakfast. I'm on a meal plan which absolutely sucks - but on Sundays I get to have a cheat day where I go buck wile and eat In-N-Out Burger. Then I'll work out, go to a vocal lesson, run through the entire set at rehearsals, go to dance rehearsal until 10 p.m. and then go home and sort through e-mails concerning the production. I feel like I'm training for the Olympics."

Now that we know details about her regimen, what can we expect from her show? From the sound of it, lots of costumes.  It requires 15 outfit changes and she notes it'll "smell like you're in cotton candy heaven." She adds, "I have this whole thing in my show that is about candy and cupcake and meat. It's both really sweet and shocking, but not in a sexual way."
