It’s no wonder Katy Perry is up for three statuettes at this weekend’s Billboard Music Awards—she puts her heart and soul into everything she does.

The hard-working singer and songwriter is currently wrapping up the sold-out Asian portion of her Prismatic world tour and will headline Brazil’s Rock in Rio concert this fall. Fearless in her desire to try new things, Perry is also now a CMT Music Awards frontrunner for her CMT Crossroads collaboration with Kacey Musgraves. And if you missed all the sexy costume and wig changes during her recent EPIX concert special, it will be out on DVD soon.

We recently caught up with the blue-eyed beauty at a red carpet event and screening to ask about staying fresh, late-night snacks and perfect dates. Oh, and hair color, of course.

“My operating hours are very strange. I’m not a nine-to-five girl, in a Dolly Parton kind of way. I’m like a nine p.m. to five a.m. girl.”

How do you stay “on” every day?
I’m not on every day. I’m sometimes 85 percent but I try my best. I always prepare myself, my mind, my body. I’m looking after my health which is most important because if I get sick I can’t play a show, and thankfully I’ve not gotten sick!

You have done so many shows already. How do you keep things fresh?
It’s really hard because sometimes there are people on the road that are sick. There’ve been puke buckets on the side of different instruments and hidden behind different lifts and things like that. And sometimes people are lonely, sometimes people have personal things going on in their life. I think you just have to continually remind yourself that these fans have waited so long, they’re probably not going to see this show ever again, they may not ever see you ever again, this is like their once-in-a-lifetime opportunity. So we always try our best and are really grateful that we have such a successful tour. From the California Dreams tour to the Prismatic world tour it’s grown so much and people still want it. That isn’t always the case, so we’re seizing the moment for sure.

How long does it take you to get ready to perform?
The shows are typically at nine p.m. and when it’s show day it’s all reserved for the show. So I sleep a lot, that’s kind of like where I get all my strength and rejuvenation. My operating hours are very strange. I’m not a nine to five girl, in a Dolly Parton kind of way. I’m like a nine p.m. to five a.m. girl. I really start my day about noon and end my day about three a.m. So I’m getting quite a lot of sleep. It’s about nine hours, sometimes even more and there’s a regime that I start from the moment I wake up usually.

What are you going to do when you finally do get time off? Are you good at switching off?
No. You have to place me on a deserted island with no phone and I’ll already probably have like a phone hidden in some box! But I  love what I do. I have a lot of energy now, things will change. I think this summer it will be very important for me to kind of step outside of my world and my bubble and have real genuine normal experiences and go to the farmers market and pick out fruit.

What’s your favorite late night snack after a show?!
Well I try, I really try on the road to keep it all very healthy but the crew always has pizza around so I’m always like ‘Give me a slice bro! Give me a slice. I’ll give you an extra hour’s sleep if you give me a slice!’

What’s your idea for a perfect date?
Oh, perfect date is really just so simple. I like connection, good conversation and jokes. I love jokes and I just like really good food and dinner and maybe a movie. I love a documentary. So it’s really simple, and oh I also like to hike.

What’s been your favorite hair color?
I actually really liked my green phase.
