Ora, 21, is a member of Jay-Z's record label company Roc Nation and is dating Kardashian's younger brother Rob and Kardashian recently tweeted about her brother's need to have a good girl in his life, reported Sun online.
"Jay-Z and Beyonce aren't impressed either since she tweeted about her brother Rob needing a good woman even though he's dating Jay's Roc Nation singer Rita Ora. "She can't resist self-promotion.
She even turned her condolences over hip-hop manager Chris Lighty passing away into a plug for a perfume they worked on together," a source said.
