And now the notoriously private star is clearing things up by lauding Hadid as "the most amazing woman I've ever known" and coming for the rumour mill - without holding back.
"To any dumb f**k out there that wants to make they're [sic] own stories up.
"My tweet was not about @GiGiHadid so leave her the f**k alone she is the most amazing woman I've ever known.
"And does nothing but love and support me when lord knows I don't deserve it.
"So if you have anything to say @ me and I'll put you the f**k straight.
"If you know nothing shut your f*****g mouth," he finished.
Zayn's rant comes after Gigi hit back at the press for suggesting she is in a new relationship with Fyre Festival booker Samuel Krost.
The pair were photographed together last week but the model made it clear they are nothing more than friends.
"If you outlets are going to continue writing bs headlines every time I'm seen with a friend of the male gender then there's gunna [sic] be a lot of unneeded confusion," she tweeted yesterday.
Some believe Zayn's words are directed towards his former band mate Louis Tomlinson.
The pair's relationship deteriorated after Malik bowed out of the world famous group.
He failed to make an appearance for Louis' X Factor performance following the tragic death of his mother Johannah Deakin in 2016, something Tomlinson admitted "really bugged" him.
"I had a couple of calls with him after I lost my mum. All the boys had agreed to come to that performance, and he didn't show so that really bugged me.
"It was just seeing everyone there - Harry, Niall, Liam - that was what I needed, that support. So on the other end of the spectrum it kind of really showed," he told Dan Wootton's podcast at the time.
