Henry Lee Hopper, the 21-year-old son of famed Hollywood film actor Dennis Hopper, is reportedly being accused of raping a 15-year-old girl.

According to a lawsuit obtained by TMZ, Hopper overwhelmed the girl with drugs and alcohol before he allegedly forced himself on her.

Hopper, a Hollywood actor who was cast as one of the lead stars in 2011's "Restless," is being sued by the mother of an unidentified 16-year-old girl. The girl apparently met Hopper though a mutual friend in February of 2011.

According to legal papers filed recently, the girl, who is being identified as Jan Doe, is claiming that she and Hopper began speaking via Facebook and eventually met in person after Hopper invited her to his home in Venice, CA on multiple occasions with the promise of drugs and alcohol, TMZ reports.

The suit then goes on to claim that the actor "preyed upon a young impressionable child, suggesting that he cared for her, luring her into his home with promises of alcohol and illegal drugs, and then repeatedly taking advantage of her youth an vulnerability."

The victim's mother is claiming that her daughter suffered "significant damage to her emotional health, strength and activity and was required to employ multiple mental health care professionals for treatment," according to TMZ.

Henry Hopper was born in 1990 to "Easy Rider" star Dennis Hopper and Katherine LaNasa.

The young actor started acting classes at age 14 and made his film debut in the 1996 film "Kiss and Tell."

Hopper did not act again until 2011, when he was cast as one of the lead stars of "Restless" by Gus Van Sant, opposite Mia Wasikowska and Ryo Kase. The film was screened in the Un Certain Regard section at the 2011 Cannes Film Festival and was released on Sept. 16, 2011 in the United States.
