Superbad star Christopher Mintz-Plasse managed to make this mama bear pull out her paws after he made a crude comment about her daughter.
The actor, 35, has a reputation for ruffling people's feathers - including those of his co-star Jonah Hill, who famously described him as 'really annoying'.
He's also previously come to verbal blows with an 'obnoxious' sports commentator after 'calling out' his lack of professionalism during an awkward interview.
But his sit down with US news anchor Rosanna Scotto really takes the biscuit, as things ended up getting physical between the pair.

As a comedy star, Mintz-Plasse obviously enjoys pushing the boundaries, but the Fox 5 host made it clear she wasn't a fan of one of his wisecracks during a 2009 interview.
The actor, 35, was promoting the film Year One, an adventure comedy he appeared in alongside stars such as Jack Black, Michael Cera, Oliver Platt, David Cross and Vinnie Jones.
He was chatting to Scotto, 67, about the flick's upcoming release on Fox's Good Day New York, when their light-hearted banter suddenly got a bit too personal for the reporter's liking.
Take a look at this:
She had asked Mintz-Plasse whether his mother still comes to visit him on set during filming, to which he replied: "Yeah, she comes, she flies to Toronto to visit me. She loves me and she likes to support me."
So far, so good, right?
Scotto then asked whether rumours about his mum sitting in on him shooting a sex scene in Superbad were true, pointing out that she thought it was a 'little strange', being a mother herself.
Mintz-Plasse saw an opening to get on the wind up, and by god, did he take it.
Feigning innocence, he then responded: "Yeah, that's not normal? Moms don't sit in on their kids having sex?"
Giggling, Scotto said: "I don't think so!"
Mintz-Plasse then hit back saying, "Come on! You've seen your daughter have sex."
Scotto's motherly instincts seemingly know no bounds, as she then reached over and playfully slapped the actor's leg - leaving him squirming in his seat.
She told Mintz-Plasse: "Hey! My daughter has not!"
Crew members could be heard breaking into fits of laughter as the TV host put the California-born star in his place, while Mintz-Plasse was seen trying to disguise a smirk which appeared to creep across his face.
In a bid to get the interview back on track, Scotto then said: "Christopher! Let's talk about Year One."
Reflecting on the now-infamous moment in 2021, the news anchor admitted: "I did lose my mind. He's lucky he didn't get punched in the nose!"
She clarified that she had actually struck Mintz-Plasse on his calf as he sat with crossed legs, before telling her co-host: "Thank you so much for bringing that up again because now I'm really angry."
