Katy Perry has admitted that since splitting from John Mayer last month she has been pushing herself to try new things.
"I'm challenging myself again, pushing my limits as I do, as a Scorpion does," she said.
The Firework singer is about to go back on tour and confesses that she believes this will be the best tour so far.
"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 it's obviously not based on candy. It's grown up. It's more mature."
The 29-year-old also added that she has decided to start a new, and expensive hobby.
"I'm going to slowly become an art collector," Katy told E! at MOCA’s 35th Anniversary Gala.
"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."
Katy went on to add that as well as pop art she loves photography as well.
Katy Perry and Miley Cyrus
"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."
Katy recently got into Twitter banter with Miley Cyrus calling the Wrecking Ball singer’s tongue "infamous", leading to Miley to respond with: "Girl if ur worried abt where tongues have been good thing ur ex boo is ur EX BOO cause we ALL know where THAT's been", following it up with: "Dontchyouuuu act like you didn't lurvvvvv it @katyperry."
Luckily it was all a joke as Katy replied with: "Oooo gurrrl I'm gonna give you the BIGGEST spanking when I see you in the UK bb!"
