Is this the disgusting act behind Zayn and Gigi break up?

FANS were blindsided by news overnight that Zayn Malik and Gigi Hadid had decided to part ways.

But shocking new photographs showing Malik engaging in a nasty habit had us wondering whether the real reason for the split was Gigi was simply too grossed out to carry on.

The official story, according to reports, was that their often long distance relationship buckled under the additional pressure of clashing, busy schedules.

The glamorous duo confirmed the news with separate tweets in which they spoke of their respect and admiration for each other.

But since then, a series of paparazzi shots showing a Zayn “looking forlorn” outside his Miami home have emerged and frankly, some of them are downright disgusting.

It’s not because Zayn is shirtless, or smoking a cigarette. These are bad habits in themselves.

No, the photos show him flexing his decorated biceps and puffing away on a cigarette before leaning over, placing one finger over his nostril, and blowing out a massive wad of snot.

The snot can be seen flying in different directions in several frames.

Bizarrely, the pop superstar, who was formerly a member of boyband One Direction,doesn’t seem fazed about getting snapped in the act and although poised close to the house seemed uninterested in ducking back inside for a tissue, a square or two of toilet paper or even (last resort) a paper towel.

So fans, if you really care about Zayn, send him boxes of tissues en masse, not to wipe away his tears but to blow that nose.
