Oh, man. Chris Pratt took to Instagram on Friday, Dec. 1, to alert fans of a “potential predator” who set up a fake Facebook account using the handsome actor’s name. The 38-year-old shared a screenshot of the imposter page, accompanied by a very heated message aimed at the person attempting to steal his identity.

“PERVY DUDE ALERT!!! (Not a joke) It’s confirmed: somebody is trying to pretend to be me on Facebook (and maybe other social media platforms) apparently hitting on a lot of different female fans, trying to get their numbers and who knows what else. I’m not joking,” Chris wrote. “Please know, I find this behavior reprehensible.”

The dad-of-one — who shares son Jack, 5, with estranged wife Anna Faris — went on to say that he will make sure that the page is taken down immediately once he finds out who the culprit is. “If I find out who it is I’ll have their account shut down and seriously would like to punch them right in the GD mouth,” he continued. “You hear that imposter!? Stop.”

The Parks and Recreation alum, whose real Facebook boasts 3.7 million followers, also told fans to keep an eye out for odd messages from the fake account, adding that they are in no way legit unless they come from his own verified page with a blue checkmark. “If there is no checkmark by my name that person is an imposter. I’m sorry,” said Chris, who is fearful that young kids might “fall for this.”

“Makes me sick. It terrifies me to think someone could be hurt, their feelings or much worse, by this imposter/potential predator,” he said. “I’ve had many, many people tell me about this. It’s not an isolated incident. If anyone is in contact with this person block them immediately.”

The Jurassic World star concluded with a stern warning to the person behind the false page: “Stop right now or you will be very unhappy with the outcome. Go find Jesus. ? praying for you.”
