"If it’s you doing it, I’m warning you. Stop right now," is Chris Pratt's message to the impostor he says is hitting on his female fans on social media.

The "Jurassic Park" and "Guardians of the Galaxy" star posted on his official Facebook page early Friday morning, beginning with the warning "PERVY DUDE ALERT!!!"

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."

Pratt said fans should look for the blue "verified" checkmark to find out if a Facebook profile is really his. He asked people to educate their siblings and other young people about the scam.

"It terrifies me to think someone could be hurt, their feelings or much worse, by this imposter/potential predator," he wrote. "I’ve had many, many people tell me about this. It’s not an isolated incident."

Pratt expressed anger toward the perpetrator, even saying he would like to "punch them right in the GD mouth." But he ended his post by saying, "Go find Jesus. praying for you."
