Good riddance, Rob Kardashian! Rita Ora is moving right along. The singer, whom Kardashian publicly humiliated over Twitter with thinly veiled cheating allegations, has yet to comment on what went down between her and the reality star-turned-sock designer. That may be because she has a new love interest! Who's the lucky guy?

Ora is said to be the apple of 'X Factor U.K.' star James Arthur's eye. The pair met when she performed on the show last month and reconnected at the final episode last weekend. A source told Now magazine (via Entertainment Wise), "He was quite taken with Rita after Saturday's show. They were getting very chatty backstage and exchanged numbers. He seemed interested in getting to know her better." Cute!

Apparently the feeling is mutual. Ora told host Dermot O'Leary, "I have to tell you the truth, I love watching James Arthur perform."

Ora has said before that she's never been in love (and chances are there's no longer any love lost between her and R.K.), but there's a first time for everything. Get it, girl!
