Conor McGregor pointed out UFC star Paddy Pumblett's weight gain while the pair spoke on FaceTime as Paddy enjoyed a visit to his Dublin pub.
Pimblett stopped off at the Black Forge Inn with a couple of his friends, coaches and friend Molly McCann.
The Liverpool native ordered a steak and burger from the menu before speaking to McGregor, who has been filming his Hollywood debut in the Dominican Republic.
McGregor was quick to point out the Pimblett had packed on the pounds.
He said: "You're already putting all that weight on again, lad! It's crazy because your face is way different straight away."
Pimblett, who is no stranger to going on post-fight binges, responded to McGregor: "Yeah, I'm back up to 191 pounds already."
He has lost weight since stepping on the scale at 206.6lb during a recent episode of TV prankster Steve-O's podcast Wild Ride .
Pimblett's weight would classify him as a UFC heavyweight at the time, but he has trimmed down to just above the middleweight limit in recent weeks.
'The Baddy' has admitted that his weight fluctuations in and out of training camp have left him with an eating disorder.
"I've had party days. I've been bad then. I got into gambling a little, and I was bad with that. I think now it's moved on to food. I genuinely think I'm a food addict," he said.
"I think I've got a bit of an eating disorder because of MMA. The weight cuts, dieting, I genuinely think I have a bit of an eating disorder. People, when they go eat with me, they are visibly shocked at how much I can eat."
McCann also spoke to McGregor on the phone as she said: "Conor, you're a f***ing belter lad," before showing off her new veneers.
'Meatball' asked the former two-weight champion if they could have a 'lock-in', with McGregor replying, "then we'll get it".
Pimblett will face another hefty weight cut if he is to compete again before the end of the year, with 'The Baddy' previously outlining his hopes of fighting on the UFC 282 card in Las Vegas on December 10.
While McCann looks to push herself further up the women's flyweight rankings when she faces top prospect Erin Blanchfield, at UFC 281 on November 12.
