Taylor attempts to become a two-weight undisputed champion when she steps up to challenge Chantelle Cameron on Saturday.
And it will be Ireland’s first boxing event since 2014 and the only time Taylor has fought at home as a professional.
So UFC superstar McGregor would not miss the occasion for the world as he spoke out on Twitter to say he will be there.
He tweeted: “What’s the story folks I’ve a couple of mega Katie Taylor announcements coming all this week, for our Katies fight!
“Multiple days back to back! But first I want to announce that I have 22 tickets to the fight itself, in the exclusive “G Cash” seats.
“I only need one seat myself.…”
McGregor, 34, has been a huge supporter of Taylor’s career and has watched her fight from ringside before.
The women’s lightweight queen was due to rematch Amanda Serrano, 34, following their fight of the year contender last year.
But Serrano pulled out injured and instead returns on August 5 in Texas in a rematch with Heather Hardy, 41, who she beat in 2019.

So Taylor, 36, instead turned her attention to Cameron, 31, and the super-lightweight titles.
And the historic fight will be sponsored by McGregor’s Forged Irish Stout.
He said: “I’m incredibly proud and honoured to support Ireland’s own, the pound for pound GOAT, Katie Taylor!
“Katie’s fight this weekend in Ireland is going to be one for the books and I’ll be cheering her on.
“Eddie Hearn and Matchroom Boxing have done a fantastic job putting together an unforgettable event and Forged Irish Stout is ready to take over fight week!”
