Katy Perry is planning to become an art collector.

The 'Teenage Dream' singer has decided to add another string to her bow by investing in fine art after becoming interested in the expensive hobby thanks to Beverly Hills gallerist Marc Selwyn.

The newly-single star told E! News: ''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.''

It seems Katy, 29, might have found a passion she enjoys as much as music and was thoroughly impressed with Los Angeles' art hotspots, where she saw works by the likes of Pablo Picasso, James Turell, Roy Lichtenstein and Jeff Koons.

She explained: ''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.''

However, the 'Roar' singer will have to put her newfound interest on hold for seven months because she is due to start her Prismatic World Tour on May 7 in Belfast, Northern Ireland.

She teased: ''I'm challenging myself again, pushing my limits as I do, as a Scorpion does. I'm very excited because I believe this is my best work yet as far as live performances.

''It's going to be just as colourful and fun as before, but's obviously not based on candy. It's grown up. It's more mature.''
