Britney Spears wants to collaborate with Katy Perry.

The 'Toxic' hitmaker has started working on her currently untitled ninth studio album - a follow up to 2013's 'Britney Jean' which spawned the singles 'Alien' and 'Work B***h' - and is hoping to get the 'Roar' singer to duet with her on the record along with Aussie popstar Iggy Azalea.

When asked if she was working on a new album, she told Extra TV: ''Very slowly, but progressively, yeah. It's in the works, yes, definitely.''

She added: ''I would love [to work with] Katy Perry, I would love to do something with her. And Iggy.''

The blonde beauty - who recently launched her new range of lingerie and sleepwear named 'Intimate Britney Spears' - also revealed that fans should expect a change of direction with the new record, steering away from her trademark pop sound.

Britney, 32, explained: ''I want to do something very artsy fartsy, something I've never done before.

''Even if it's just take a left lane and go for a little bit of rock or rock-pop. Just do something that's kind of out there and different.''
