It’s definitely all over for this celebrity couple!

Calvin Harris has confirmed he and girlfriend Rita Ora have split up.

The DJ took to Twitter to break the news after months of speculation their relationship was on the rocks, and said it happened “some time ago”.

Calvin tweeted, “To address speculation – myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best.”

Rita has so far stayed quiet on the break-up, so we hope she isn’t nursing a broken heart!

The pair have been dating since last May, and the 23-year-old singer even produced her latest single I Will Never Let You Down with the Scottish DJ.

The split announcement comes after 30-year-old Calvin was spotted leaving two Hollywood clubs this week with separate girls, as Rita stayed in Mexico with her family.

Ouch!
