Fans are speculating that a cryptic tweet of Conor McGregror's could be signalling that his partner Dee Devlin is pregnant.
The Notorious sent social media into a frenzy earlier this month when tweeting: "Dublin, December 14".
Many thought it was the date and location that he would make his UFC return having been out of action since last October's submission loss to Khabib Nurmagomedov.
But both UFC boss Dana White and McGregor's coach John Kavanagh have said they don't know the significance of the date.
And other social media users believe that the fact McGregor posted a family snap after the cryptic tweet indicates that it may instead of being about a new arrival.
One person commented: ‘Omg wait another baby??? When? A girl? Omg what!!!’
McGregor and long-term partner Dee have two children together with baby daughter Croia arriving at the start of the year, and two-year-old son Conor Junior.
Conor McGregor has been tipped to return in January or February by one of his teammates.
The Irishman has not fought since he was choked out by Khabib Nurmagomedov last October.
He has been mired in controversy since, knocking a phone out of a fan's hand before allegedly punching a 50-year-old man in a Dublin pub.
McGregor also broke his hand in sparring which has delayed his return to the cager.
But according to Makwan Amirkhani, the Irishman could make his comeback in the first two months of 2020.
“He’s been in the gym and he’s been working by himself a lot and I think he’s building himself up," he told MMA Junkie.
"I believe in the beginning of next year, that’s the time that Conor will step up – January or February."
McGregor admitted during an interview with ESPN last month that he has lost his way since becoming one of the richest sportsmen in the world.
And Amirkhani added: “I think in the end, Conor knows that it’s not the money that makes us athletes happy.
"It’s that we can go there and perform, and I think he’s hungry for that.
"He knows that’s the thing that makes his life happier, and that’s the thing that he loves, so I believe truly that he will get back.
"We've seen a lot (that) his mind is on a whole other level. There have been a few steps backwards, but we all make mistakes and we all learn from them.
"And I think when he gets back (to fighting) he will be another person."
