Rita Ora ‘Found Out Calvin Harris Had Broke Up With Her On Twitter'

Rita Ora was apparently the victim of a pretty brutal dumping method by Calvin Harris, according to reports.

Their relationship had been on the rocks for a while when Calvin took to Twitter to address speculation that they’d spit - however the ‘RIP’ singer had no idea he was going to go public with the news.

Posting on Twitter last week, Calvin wrote: “To address speculation — myself and Rita ended our relationship some time ago. She is a beautiful, talented woman & I wish her all the best.”

While the tweet suggested there were no hard feelings between the pair, poor Rita was left “embarrassed” by the message, according to The Sun.

A source reportedly told the paper: “It was Calvin’s decision to end the relationship. They had been arguing for months and had grown apart.

“Rita was left embarrassed when he tweeted that it was all over.

“She didn’t think he was going to make the announcement, so she was shocked.”

The Scottish DJ was apparently not too pleased with Rita’s constant Instagram posts, which always showed her with other groups of pals.

“She was constantly posting snaps of her with other groups of friends and her trip to Mexico and photos of her with Khalil were the final straw,” the source said. “Calvin likes more privacy than Rita and he hated the extra attention that came with being her boyfriend.”

The musical pair had been quietly dating for a while, though they broke up for a few weeks in January.

Rita often spoke publicly about their relationship and discussed their chart battles on Radio 1.

“It’ll be really cool if I knocked him off the top spot,” she said.

The pair also attended a number of events together in recent months, including the Grammys and the Brit Awards.
