Zayn Malik has bought his fiancée's mother a new house.

The One Direction star is engaged to Little Mix singer Perrie Edwards, 20, and reportedly decided to foot the bill for his future mother-in-law Debbie's new home in Dorset, south west England when he heard she was planning the move.

A source revealed: ''Debbie has been saying how she's got a new house.

''Perrie was going to get the mortgage for her and then Zayn offered to buy it outright.

''She is just moving stuff in now. It costs more than £200,000 and is a new build.''

Zayn has been dating his fellow pop star for two years and popped the question last summer, and her family are said to be thrilled with his latest act of kindness.

The source told The Sun newspaper: ''He's a really nice chap for buying the house.

''It's a lovely gesture ahead of their wedding.

''He gets on really well with her family.''

The 21-year-old singer, along with his bandmates - 20-year-olds Niall Horan, Liam Payne, and Harry Styles and Louis Tomlinson, 22 - have become the richest boyband in British music history as they reportedly have a combined fortune of £70 million.
