Zayyn Malik
The singer has been trying out a new look recently   Instagram

One Direction's Zayn Malik was almost unrecognisable on a recent night out when he wore a new rugged look.

The heartthrob looked a lot older than his 21 years as he partied with friends at London hotspot Chiltern Firehouse with an impressive new beard and throwback Justin Bieber hair.

Malik, who is engaged to Little Mix' Perrie Edwards, teamed his new look with a sweatshirt which featured very elaborate black and white floral prints, black jeans and black trainers.

And it looks like he has got the thumbs up from fans too.

" The shirt, the hair, the beard, i can't breathe" one said.

His rare outing comes as One Direction prepares to head to Canada to continue their world tour.

It seems the singer needed to blow off some steam after being bombarded with death threats by outraged Israelis for posting a #FreePalestine message to his 13 million followers on Twitter.

One angry fan told Malik, who was brought up a Muslim in Bradford, Yorkshire, that he should 'let me kill you'.
