Now, we're not entirely sure if this is all just 'banter' - or if the pair are actually glaring at their computer screens while sticking pins into little voodoo dolls of each other - but it's STRESSING US THE FRICK OUT.
Can't we just all have a big, naked, group hug together boys?
The twitter row/banter/whatever you want to call it seems to have been sparked by Zayn's comment two days ago, when he called Max a 'geek' for cosying up to Usher.
Max replied with: 'that's right gorgeous!' before the pair 'joked' about flirting with each other - and we thought perhaps a light was dawning at the end of the boyband rivalry tunnel.
In fact we're not ashamed to say we breathed a sigh of relief. WE BREATHED THAT SIGH TOO SOON, SCAPERS.
This exchange then happened. Which we don't fully understand.
THEN ZAYN SAID THIS. Hello, sassypants.
Now, up until this point the tweets could have all been passed off as banter. Then Tom Parker got involved, and said: 'I think "1 stripes" got his knickers in a twist'.
HEY only we're allowed to take the piss out of Zayn's (now deceased) badger quiff.
Zayn hit back with: 'Mate if I had a face like yours my hair would be the last thing I'd worry about ;)'
HEY we want to snog that face, don't be mean about it.
Unsurprisingly, Louis Tomlinson didn't stay silent for long - and leapt to the defence of his bandmate with the simple, yet sassy, '@TomTheWanted pipe down bad boy'.
Well done boys, you've woken the sasquatch.
Now stay with us, because this is where it gets a bit confusing timeline-wise. While the Zayn/Tom spat was going on, Max then replied to this earlier tweet from Zayn, saying: 'that's not very nice. I was just starting to like you and your RnB hits.'
A few minutes later, Tom revealed his extensive knowledge of the 1D boys nicknames, by posting a photo of Zayny-pops with the caption: "Bradford Bad Boi".
Just when we started to think it was all over, and we could stop screeching every time our timeline was taking too long to refresh, Zayn lept in with this final comment to both The Wanted boys (who knew he was so fiesty?)
Max replied with: '@Zaynmalik enjoy rehearsals. Stay off the bud... it clearly makes u cranky.'
OH GAHD WE CAN'T TAKE ANY MORE OF THIS. We think Zayn, Louis, Tom and Max should all take a leaf out of Nathan Sykes book - who spoke to us recently about wanting to 'sort out' the rift, and loving Niall Horan.
