Ke$ha has hooked up with Calvin Harris.
The Sun reports that the two got together when Calvin was DJing at Rihanna's gig in Australia.
A source said:' They were all over each other and didn't care who was watching.
'Ke$ha is a bit of an animal but Calvin reckons he can handle her.'
The two have known each other since Ke$ha supported Calvin on tour a few years ago.
