Katy Perry on success: 'I'm not trying to ever duplicate what I did on 'Teenage Dream''

Katy Perry believes she will never replicate the success of her album 'Teenage Dream'.

The US star released the chart-topping album in 2010 and it spawned a myriad of hit singles, such as 'Firework' and 'California Gurls'.

Speaking to Rolling Stone, the 'Dark Horse' singer said that she isn't one to obsess about notching No.1s.

Perry said: "I'm not trying to ever duplicate what I did on 'Teenage Dream', because I could never. 'Prism' is more about showing the variety I have as an artist, rather than always having a determined goal to go to Number One or whatever.

"I mean, it's always nice, but that's not always going to happen. And I don't want to have to conform to try and do that. Like, I don't want to have to play something I'm not to get that Number One or whatever. That's not music. That's math. And I don't want to be that."

Perry released her latest album 'Prism' in 2013 and it features the tracks 'Roar' and 'Dark Horse'.
