Rob Gronkowski’s poker face didn’t stand a chance when he heard a joke about Bill Belichick’s 24-year-old girlfriend, Jordon Hudson.

During an appearance on the YouTube series “Sundae Conversation” Sunday, the former Patriots tight end struggled to keep it together when host Caleb Pressley slipped in a cheeky joke about Bill Belichick’s much-younger new flame.

As Pressley quizzed the former athlete on Gronk’s post-retirement life, he mentioned that Belichick, 73, now has a new lady on his arm.

“Bill’s picked up a 24-year-old,” he told Gronkowski, who responded, “The Buffalo Bills?”

“No,” Pressley replied, “Have you met Coach Belichick’s girlfriend?”

The question prompted Gronk to burst out with laughter,

“He got me,” he laughed. “How did I fall for that one?”

It comes as Gronk seemingly implied last week that Hudson has been somewhat of a distraction for the University of North Carolina head coach.

“You know, and in the back of your head, too, you’re just thinking to yourself as well, ‘When you were on the Patriots, the whole goal was to eliminate all the distractions that can possibly happen while you’re on the team,’” Gronkowski said during a recent interview with 98.5 The Sports Hub.

“And don’t bring those distractions to the team and in the locker room, and we’re just looking down at the program in North Carolina and it feels like there are just distractions 24/7 down there. There’s no football talk as well.”

Belichick has faced a slew of questions about his relationship with Hudson in recent months — especially after she repeatedly interrupted his “CBS Sunday Morning” interview back in April.

Last week, the coach told ESPN that his relationship with Hudson is “off to the side” and that “she doesn’t have anything to do with UNC football.”

Still, he revealed that Hudson had been copied on emails from the football program since there was no one running the sports information department for the team.

“It would be personal opportunities. It could be a speaking thing, it could be an appearance on this, or talk about this, or somebody wants whatever it happens to be an autograph, or that type of thing,” Belichick told Clark on the podcast. “And so, she’d kind of help organize that for me.

“One of the first things that came out when North Carolina sent me emails saying, ‘These people want to talk to you…’ I sent back an email, ‘Can you please copy Jordon on these requests?’ so she could at least filter through them because there was nobody.

“We didn’t have a sports information guy. Because all emails are shared publicly, that was taken as Jordon’s running the sports information department. And that also led to a narrative, which is just totally — she’s not doing it. I mean, there was nobody to help me sort it out, so I was asking her to do it.”
