Ke$ha has revealed that she has made a song with hitmaker Calvin Harris.

The Scottish DJ is well used to collaborating with hit artists, with Harris previously working on the likes of Rihanna's massive 'We Found Love'.

It seems Ke$ha is going to be the next recipient of his gold dust after the singer revealed to Digital Spy that they have worked on a song togther - however, she doesn't know when it will be made available to the public. The 'Die Young' star said:

"I come to London a lot - I actually made some of the first record out here. I love it here - I love the weather, the men and the unpredictability. I even made a track with Calvin Harris that has never seen the light of day. It's a great track - I'm sure we'll release it one day!"

Ke$ha also outlined some of her future plans, which includes releasing an acoustic EP and a range of teeth-inspired jewellery. She added:

"I also have a picture book coming out which I'm really proud of, a 5-song 'Deconstructed' EP of acoustic tracks, a fake fur line and a jewellery line, which includes a teeth range. Basically I'm doing a bunch of incredibly fun sh*t."
