Rob Gronkowski was trolled about his former coach Bill Belichick‘s polarizing relationship with 24-year-old Jordon Hudson … but in true Gronk fashion, he couldn’t help but laugh his ass off over it all.

The future Hall of Famer sat down with Caleb Pressley for a “Sundae Conversation” … and at one point in the cheeky interview, the former Barstool Sports personality hit him with a quick one while pretending to talk NFL.

“The matchups this year are incredible … and there’s a lot of really exciting teams,” Pressley said. “Bills picked up a 24-year-old.”

“Have you met Coach Belichick’s girlfriend?” he asked … and Gronk started to giggle like a kid before admitting he has not.

But it didn’t stop there — CP had a follow-up locked and loaded.

“The crayon you wrote your book with — did you take that out of her backpack?”

Gronk gave props for the clever delivery … admitting he got got.

The whole segment was filled with funny moments … and there was even a back-and-forth over Aaron Hernandez.

“This is the most outrageous show I’ve ever been on,” Gronk said.
