 -- The usually humorous Chris Pratt took to social media early Friday morning to warn fans about a very serious matter.

The "Guardians of the Galaxy" star wasn't joking when he wrote on Instagram and Facebook, "PERVY DUDE ALERT!!! ... 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."

The 38-year-old actor added that he finds "this behavior reprehensible."

"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. You hear that imposter!? Stop," he wrote. He also added a photo of the fake account.

Facebook told ABC News via statement, "We are aware of the reports and we’re working to take the appropriate action to remove accounts that violate our Community Standards. It’s important for people to know that they can report any of these impostor accounts and anything that may look suspicious using our reporting tools at facebook.com/report.”

Pratt also added a warning to fans.

"Look for the BLUE “VERIFIED” CHECKMARK," he said if anyone is contacted by someone claiming to be him. "Tell your siblings. Educate our young ones. It’s probably mostly kids who would fall for this. Makes me sick."

Pratt's biggest concern was fans being taken advantage of or getting their feelings hurt by someone pretending to be him.

"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. If it’s you doing it, I’m warning you. Stop right now or you will@be very unhappy with the outcome," he added.

This week had been a banner one for Pratt with the first trailer from "Avengers: Infinity War" hitting the web and garnering more than 200 million views.

The blockbuster Marvel hit comes out next year and not only features Pratt's fellow "Guardians," but the rest of the universe as well, including Spider-Man, Iron Man and Captain America.
