Zayn Malik ended his engagement with a text message.
The former One Direction star reportedly told his fiancée of two years, Perrie Edwards, it was over by sending her a message two weeks ago and hasn't been in touch since.
A source said: "It's unbelievable, he's an immature little boy with no thought for anyone else's feelings. Perrie is one of the sweetest girls in the world and she's stood by him through thick and thin.
"But he ended their engagement with one text message and in the two weeks since there's been complete radio silence between them. Who does that? She's devastated, which everyone understands, but is doing her best to focus on work and to put on a brave face in public."
And now the pair are said to be squabbling over the recent purchase of their £3 million home.
The insider added to The Sun newspaper: "This was the house where Perrie expected to marry Zayn and act as his wife for the rest of their lives. It was their dream home and he went through with the purchase only a few weeks ago. They bought the house from a Premier League footballer and both loved it.
"It's understandable that Perrie feels confused and led on. He must have already been having doubts about the relationship. This was a very serious, major financial purchase. She thought Zayn was committing to their long-term future."
