Britney Spears has teamed up with Iggy Azalea.

The 'Toxic' hitmaker - who is currently in the middle of her two-year residency show 'Britney: Piece of Me' at Planet Hollywood in Las Vegas - will release the ''undeniably great'' track with the Aussie-born star early next year.

Iggy, 24, confirmed the news to the Daily Star newspaper: ''We have a song which is going to be her first single coming out next year. It's undeniably great. It's a really fun track.''

Britney - who is currently working on her ninth studio album - has previously expressed her desire to work with the 'Fancy' singer, as well as 'Roar' hitmaker Katy Perry.

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

The currently unnamed track will be the 33-year-old's singer's first offering since the release of her eighth studio album 'Britney Jean' which, despite spawning the hit singles 'Alien' and 'Work Bitch', became her lowest-selling record of all time.

She also hinted that fans should expect a change of direction with the new record, steering away from her trademark pop sound, saying: ''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.''
