The lawsuit filed shows the 21-year-old actor is being sued by the mother of the unidentified girl who is referred to as “Jan Doe”.
Hopper reportedly met Jan Doe through a mutual friend in February 2011 and they began talking on Facebook.
Henry invited the 15-year-old girl to his home in Venice, CA on several occasions, where he would give her drugs and alcohol and engaged in sexually assaulting her.
Insiders report Hopper specifically engaged in “sexual intercourse, forced oral copulation, and sodomy” with the teen.
Doe’s mother is suing for unspecified damages, claiming her daughter suffered injuries to her mental health.
Henry is an actor who appeared in Gus Van Zant’s “Restless” and “Tree of Life”.
His father Dennis died at the age of 74 in 2010, following a battle with prostate cancer.
