Rita Ora was embarrassed after she learnt about her break up with Calvin Harris via Twitter, media reports said, citing sources.

Harris recently announced his break up with the 23-year-old singer on Twitter, while reports claimed that Ora was surprised after the revelation because she had no clue that the 30-year-old Scottish singer-songwriter would choose to end the relationship on the microblogging site.

"It was Calvin's decision to end the relationship. They had been arguing for months and had grown apart," the source reportedly said. "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."

An insider reportedly told British newspaper The Sun, in an interview: “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. Calvin likes more privacy than Rita and he hated the extra attention that came with being her boyfriend.”

Ora and Harris had reportedly broken up for a few weeks in January after dating for about a year, following which they again restored their relationship until finally calling it quits early this month.

Ora, who was recently linked to Canadian singer Justin Bieber as well as his friend, American singer Khalil, was previously dating Rob Kardashian. Her relationship with Kardashian reportedly ended in 2012 after he accused the “R.I.P.” singer of seeing other men.
