Conor McGregor left fans stunned as he showed off his new physique after sharing snaps of his surprise reunion with Justin Bieber.
The former two-weight UFC world champion looked unrecognisable in recent photos and huge compared to his usual body after bulking up during his recovery process from a broken leg.
The MMA fighter is allegedly weighing as much as 190lb and avid followers say he looked "massive" in photos where he ran into Canadian pop star Bieber in the Caribbean.
As reported in The Mirror, WWE star Sheamus noted that the Irishman was now "Wrestlemania sized", while other fans added that he has a "proper bulk on".
One fan joked: "Mate, the size of you - f***ing hell," while another said that he looked like the villain Bane from the Batman comics.
McGregor and Bieber have been pals for a long time, but rarely get to spend many hours together given their packed schedules.
The singer is one of the most famous individuals in the world, while McGregor is also incredibly busy as an owner of multiple businesses, even during his off-time from the sport.
But they are very friendly when they do see one another, with the Irishman even flying to New York in the past to present Bieber with an award.
"I bumped into Justin Bieber again today," McGregor said in his post. "In the Bahamas! I always randomly see Justin out of nowhere and just chop it up, I love this kid!
"Two goats [Greatest Of All Time] on a cliff sideways, just chopping it up, what’s happenin' JB my brotha hahah.
"I put it up to the sky this keeps happening, it’s something from above that keeps doing this!
"God bless you my brother, great to see you always. Some serve today!"
McGregor is currently on the comeback trail after suffering a severe injury at UFC 264 that has put him out of action for the best part of a year.
He is still unable to train MMA in any way, and while it is expected that he will return to the octagon this year, it would be hoped that he can be back in a cage for sparring soon.
In the meantime, he has spent a lot of time at his Dublin pub The Black Forge Inn, concerning fans with certain posts after declaring that he is soon to give up his whiskey Proper 12 as well as his new Forged Irish stout.
McGregor had been aiming to get an immediate title shot on his return, but that is looking increasingly unlikely after the Charles Oliveira was booked to fight Justin Gaethje.
Oliveira, a fighter who has struggled for big money fights over the years, has said that he wants to face McGregor next, but it now seems improbable.
Instead, the Irishman could face one of Nate Diaz, Tony Ferguson or even Poirier for a fourth time when he steps in again.
