In case you weren't aware, the Hollywood superstars have a long-running beef, which has manifested itself through countless social media prankings and trollings down the years.
And when Reynolds and Rob McElhenney announced they were planning on buying Welsh fifth tier club Wrexham, you could be forgiven for assuming it was just another joke.
However, the seemingly bizarre acquisition became a reality in February when the actors took 100 percent control of the Red Dragons.
Now though, Jackman has seen an opportunity to get one over his faux foe.

When LADbible put it to the Aussie that he could take over his own British football club, purely to defeat Wrexham, he replied: "I had never considered it - until just that last bit of that sentence."
The Wolverine actor - who stars in new sci-fi flick Reminiscence - then went one step further, suggesting he could buy Norwich City in order to go head-to-head against Wrexham in a winner-takes-all match.
The 52-year-old said: "Let's get that game together. That'd be fun.
"And then maybe Ryan and I could just make it a little side wager. Like, everything; let's just put everything that we own and love - families, kids, everything - on the line. And let's get Norwich playing Wrexham."
So, this might seem like a totally bizarre idea - and it obviously is - but it's not quite as random as it sounds.
Jackman's mum lives in Norwich and he considers himself an honorary Canary, having been to a couple of games at Carrow Road.
In fact, he said celebrity supporters Delia Smith and Stephen Fry once wrote to him offering up the opportunity to invest in the football club, but he turned it down.
Perhaps then the prospect of Reynolds' Wrexham taking on a Jackman-led Norwich isn't as far-fetched as it initially sounds.
However, Reynolds thinks it would be best for Jackman - and Norwich - if this didn't happen.
Responding to Jackman's proposition, Reynolds told LADbible: "I don't think that's a wise idea.
"I mean, you know, Hugh has the business acumen of a slug. So I don't think that would go over very well."
He added: "I would back Wrexham to beat just about anybody, if you just give us a little time."
