Split After Getting
"Touchy Feely" With


Who would have thought the man behind Rita Ora and Calvin Harris' split was Justin Bieber? That's right. The Biebs is reportedly to blame for their break up.

The 20-year-old pop star triggered the end of the couple's relationship after he became "affectionate" with the 23-year-old singer in a recording studio a few months ago.

"Word got back to Calvin, Justin and Rita got touchy feely with each other while they were in the recording studio together over the last few months," a source alleges.

"Calvin heard they were very affectionate -- she would sit on his lap [and] he would rub her back."

Rita moved in with Calvin, who produced her new track I Will Never Let You Down, in LA, but he's now had her belongings removed from his home.

The source explains, "He's already had her things removed from his LA house...he [also] produced a few songs for her, but now he won't allow their release."

However, the 30-year-old Scottish DJ took to his Twitter account on Friday to announce that he and Rita, whom he began dating in May 2013, had separated "some time ago," but he wishes her "all the best" in the future.

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

Meanwhile, Calvin appears to be surrounding himself with his friends following the split as he was spotted dining with a group of pals - including Rosie Huntington-Whiteley - in West Hollywood on Thursday night.
