Stefon Diggs was just bombarded by questions about his now-infamous May boat ride … but the New England Patriots star rebuffed them all — saying he wanted to keep his “personal life personal.”

Diggs met with reporters on Tuesday for the first time since he was seen on video appearing to offer a pink substance to bikini-clad women on a yacht over Memorial Day Weekend … and it didn’t take long for the journalists to unleash queries about the incident.

They first wanted to know what exactly was in the bag in the footage — but Diggs, who had just wrapped a workout with his new team, declined to get into any sort of specifics.

Diggs did acknowledge he had a conversation with Pats head coach Mike Vrabel and others in the organization after the video had circulated widely on the internet … but he said, “the particulars is all internal.”

Reporters, though, still asked several follow-ups about the matter … but Diggs turned down each one.

“I don’t want to be rude,” he said, “but I would hate to repeat myself for the fourth time. You want me to repeat myself again? And say the same thing again?”

While Diggs clearly wasn’t amused by it all — Kevin Hart found a way to make light of it on Monday … joking about it during the BET Awards.
