A new report is claiming hot-headed-actor Charlie Sheen is allegedly the baby daddy of a young man who has striking resemblance to the star.

TVNotas and msn now are reporting that a 22-year-old, Sverre Willumsen called out Charlie Sheen via his Facebook page, demanding that he take a paternity test to prove once and for all that Sheen is in fact his biological father.

Willumsen posted up a photo of a sign that states how Sheen and his mother allegedly met. He also asks for people to sign his petition to pressure Sheen into doing the paternity test.

“23 years ago my mother worked as a stewardess in the U.S.,” read the poster. “I found out a couple of months ago that she had sex with Charlie Sheen.”

“I was watching anger management (crappy show btw) the other day and then looked at myself in the mirror and thought what the f**ck!!! I don’t know who my father is … if I get 1,000000 likes Charlie Sheen is going to get a DNA Test.”

Willumsen, who lives in Norway, has Sheen’s facial expressions such as the same eyebrows and nose and even the same smile.

Sheen has five children, which include a 28-year-old daughter who is currently pregnant, two daughters with fellow actress Denise Richards and a set of twins with Brooke Mueller.

Recently Sheen made headlines and it wasn’t for his hard partying ways or off-the-wall temper tantrums.

As Fox News Latino reported, the actor wired $10,000 to Teagan Marti and her family for a therapy dog to help in her rehabilitation from injuries sustained when she plummeted 100 feet from a Wisconsin amusement park ride in 2010.

"I think he's a very kind person for helping me and my family, and very generous," Teagan Marti said from her home in Parkland, Fla.

Teagan Marti suffered brain, spine, pelvis and internal injuries in July 2010 when nets and air bags that were supposed to catch riders on a free-fall ride were not raised.
