Pop star Katy Perry feels like "a toddler" when she wraps up a tour - because she has to make her own decisions about where to eat and how to live.
The California Gurls hitmaker admits all decisions on tour are made for her by a road manager - and it's often a big shock to fend for herself again when the touring ends.
She explains, "You get so used to having transportation or a hotel room, and it becomes, 'Do I eat food now? How do I get to the movie theatre?' I'm a toddler."
And upcoming tourmate Robyn, who recently interviewed Perry for Entertainment Weekly magazine, agrees: "When you're on the road, the tour manager tells you when to eat and where to go and how long you have to wait for something.
"When I'm left at the airport to go home, everything stops functioning for me."
