The 23-year-old singer, who spends her spare time on tour watching crime TV shows such as 'CSI', said if she becomes a police sleuth she does not think she would be a very good one, reported Contactmusic.
"I'd be an interior designer or a detective - but I don't think I'd be a good detective. I just watch all of those crime shows. Anything that has a slight premise of being a crime show, I'm on it. I have so many boxsets - I'm into 'Criminal Minds' at the moment, and 'Law And Order', and 'CSI'. I've never seen The Wire but I'll get into that next," she said.
Despite her hectic touring schedule, the 'I Knew You Were Trouble' hitmaker insists she enjoys life on the road.
"I think it's hard the first couple of years. But once you get into the groove you kind of just get used to it. In fact you get a little restless when you're in a place for more than two days. You start thinking, 'When am I supposed to board a plane?' and, 'When am I supposed to pack my stuff?," she said.
