Katy Perry would love to study history.

The 'Dark Horse' hitmaker has revealed she would be keen on returning to education to learn about world history as she feels it would benefit her future.

She told Forbes magazine: ''If I could go back to school, I would study history.

''I'd study world history, just to know how people work, and how they evolved, and where we come from. I feel like when you know about what happened in the past you can do better for your future.''

The 30-year-old star previously revealed she wanted to become an art collector after being inspired by Beverly Hills gallerist Marc Selwyn.

She said: ''I'm going to slowly become an art collector. Today, we had an all-day art crawl. We got to see some private collections from some people's homes and then we went to a couple of galleries.

''What I'm really drawn to is modern contemporary art and pop art, of course. Also some key photography. I've always loved Cindy Sherman and today I got interested in Lee Friedlander...

''This is all brand new. I'm really interested in having an art history education. This is all brand new. I'm really interested in having an art history education.''
