The 26-year-old singer, who is currently traveling the globe with her California Dreams tour, said that when she is on the road, her manager makes all the decisions when it comes to when and what she eats and how she lives.
Being interviewed by tour mate Robyn for Entertainment Weekly, she explained, '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.'
Robyn added, '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.'
