Justin Bieber is now no stranger to controversy: While he is currently dealing with all the criticisms following the emergence of his two racist videos, the troubled singer is reportedly the one to blame for the recent breakup of Rita Ora and Calvin Harris.

Ora and Harris, who began dating in May 2013, were last seen together when they were taping "Watch What Happens Live" in New York City at the end of April. Also, the song they wrote and produced together, "I Will Never Let You Down" became number one in the U.K.

It has recently been reported that the Canadian pop star sparked the couple's split after he apparently got cozy with the British singer. "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 said. "Calvin heard they were very affectionate -- she would sit on his lap, [and] he would rub her back."

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

After he had been spotted partying with different women over the last week, the Scottish DJ took to his Twitter account on Friday, May 6, to officially announce his split with the "R.I.P." hitmaker. "To address speculation - myself and Rita ended our relationship some time ago," he tweeted. "She is a beautiful, talented woman & I wish her all the best."

In addition, Ora previously spoke about the challenges of long-distance relationships. "You have to fly each other out, you just have to," she said. "Sometimes you fly for 20 hours, sometimes you only fly for five hours. It's an effort, but you make it work."

"I'm not a fan of long distance relationships," she said. "If you had a choice, you want that person with you. It makes me pretty sad. But you work with what you've got."
