Calvin Harris seen hanging out with his famous ex-girlfriend

Eek! We’re not so sure Rita Ora will be too happy about this!

Calvin Harris has been uploading selfies – with his ex-girlfriend Kesha.

The two were partying in Las Vegas when Calvin uploaded the photo to his Instagram account.

We’re sure Rita is secure in her relationship with Calvin – but is it ever easy to see your boyfriend with an ex?

Calvin first started seeing Kesha back in 2011 and the two have apparently remained close despite the relationship not working out.
