While her face is either hidden by her hair or she's seen in the background of the pics snapped of Harry (Daily Mail has a roundup of photos), it looks like it could be Ariana Grande's Victorious co-star Daniella. Did Ariana play matchmaker after Harry wrote a song for her new album? Hmm.
Neither of them mentioned it on Twitter, but Daniella did go to a recent One Direction concert at the Rose Bowl and shared a pic of Harry on stage.
One small thing to point out...Daniella has a boyfriend, right?
Maybe they were just hanging out as friends. Or maybe it's not really Daniella after all?
