Niall Horan has reportedly split from Zoe Whelan.
The One Direction heart throb has ended his on/off relationship with the Irish model, which started in March, and it is claimed he has been "blanking her" by severing all ties.
A source said: "It is all over for Niall and Zoe - and it is completely because of his side of things.
"Obviously, it was always going to be hard to have an ongoing relationship when his job has him travelling around so much.
"But there's been no push from Niall to keep things going at all and has told Zoe it is over by completely blanking her."
With the 18-year-old beauty's career is starting to go from strength to strength however, the 'Little Things' hitmaker hasn't been in touch to offer his congratulations or support.
The insider said: "Over the past few weeks her modelling career has become huge, but Niall hasn't been in contact to say well done. She hasn't even had a text from him, let alone a call, for nearly two weeks.
"Out of respect to Niall, she refused to say a word to anyone about the relationship, even when there was money on the table to spill the beans as she knew it would be over then.
"But it seems just doing her job is too much for 1D's people, who appear to have pressured Niall to cut all ties with Zoe. It's cruel the way he's done it, and she's obviously a bit devastated it's over."
