Rita Ora splits from Rob Kardashian - report

Singer RITA ORA has split from KIM KARDASHIAN's younger brother, according to a U.K. report.

The R.I.P. hitmaker initially played down rumors she was dating Rob Kardashian this summer (12), telling Complex magazine, "It's not really a relationship. It's not that intense. He's a cool guy. We're close. We're good friends. I got his back and he's got mine."

Kardashian fueled gossip in October (12) by posting a picture of the pair kissing on his Twitter.com account, but now Britain's The Sun newspaper reports the pair has parted ways after struggling to find time for each other.

A source tells the publication, "It's really sad - they really liked each other but with him living in L.A. and her over in London, it was becoming impossible to maintain a relationship.

"They'd only decided to go public with the romance a couple of months ago so as not to put any pressure on themselves but they've already split. Rob has now deleted everything on Twitter that reminds him of Rita."
