Chris Pratt posted to Instragram last night warning fans not to fall for an imposter claiming to be him on Facebook. He included a screenshot of the fake account and said he'd like to punch the guy "right in the GD mouth."

"PERVY DUDE ALERT!!! (Not a joke)," he wrote. "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. Please know, I find 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. My message to any fans who are contacted by someone claiming to be Chris Pratt: Look for the BLUE 'VERIFIED' CHECKMARK next to the name. If there is no checkmark by my name that person is an imposter. I'm sorry."

If there is no checkmark by my name that person is an imposter. I'm sorry. Tell your siblings. Educate our young ones. It's probably mostly kids who would 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. 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. Go find Jesus. ???? praying for you.

Pratt is single again after splitting from wife Anna Faris. But it's not likely he'd be looking for love on Facebook.

For the record, THIS is Pratt's confirmed Facebook account. He goes by the user name "Prattprattpratt" on Instagram, Facebook and Twitter, not "Chris Pratt."
