Barbadian pop star Rihanna is taking a pounding, and it ain't Chris Brown or Karrueche Tran who's giving it – it's Kosovar songstress Rita Ora!

The Pristina-born, London-raised mezzo-soprano has been stealing headlines from Rihanna ever since she stole her song – literally!

Word on the street is that Drake wrote the song R.I.P. specifically for Roc Nation artist Rihanna, but Jay-Z was so upset with her musical and romantic reunion with former abuser Chris Brown, that he took the song – featuring Tinnie Tempah and produced by dubstep duo Chase & Status – from Rihanna, and gave it to Rita Ora.

A source told Radar Online that Jay-Z, who recently had a baby girl with Beyoncé, is deeply disappointed in Rihanna's decision to return to the man who beat her three years ago, punching her repeatedly on the arm and in the face, to the point of visibly bruising her face.

Jay was absolutely disgusted by what Chris did to Rihanna, the source told Radar Online. Last year at the VMAs, Jay-Z refused to clap for Chris Brown after his performance. Media reports claimed that Rihanna found solace in Jay-Z after the incident, but obviously she's had a change of heart, recording a song with Brown, cuddling with him at her Valentine's Day party, and reportedly secretly dating Brown for nearly a year, according to Us Weekly.

As for Rihanna, how is she feeling sitting under all of Rita Ora's shade?

Well, for one, we know that Rihanna doesn't handle competition well. It will always be a competition and that's why I feel like women are becoming so dominant in music right now, she told British talk show host Jonathan Ross last week. Because we're very competitive beings and we cannot stand to see another woman do better than us, that bothers us a lot.

With musical competition from Rita Ora and romantic competition from Karrueche Tran, Rihanna sure has a lot to be bothered by these days!
