in separate incidents at his Hollywood home between 2001 and 2003.
His appearance in court today was a preliminary hearing on the charges. The hearing will determine whether Masterson will stand trial on the rape charges.
Jennifer explained that the incident occurred in April 2003 and that at the time, she went to the church of Scientology to ask for permission to report the alleged crime.

The alleged victim testified that church officials said she should not report the alleged crime because Masterson was a "member in good standing."
The church also threatened to cut Jennifer off from the Scientology community and her family and friends who were members, she told the court.
She testified that on the night in question - April 25, 2003 - Masterson made her a "fruity drink" and then threw her into a jacuzzi, even though she said she didn't want to go in.
She claimed that the actor threw her in with some of her clothes still on.
Jennifer described the alleged attack in court Credit: BackGrid The actor has pleaded not guilty Credit: Alamy She said she began to feel "blurry" and disoriented while she was in the hot tub, and was helped out by a friend because she began to feel like she would be sick.
She claims Masterson carried her upstairs, where she was sick, and then proceeded to put her into the shower and wash her.
She said that she "passed out" after the shower and when she woke up, Masterson was having sex with her.
"When I came to he was on top of me and inside me. I think I was completely naked at that point," she said.
"I can recall grabbing his hair to pull him off and I also recall taking a pillow and pushing it toward his face because I could not get him off me. I couldn't breathe and I felt myself going unconscious again."

During cross-examination, Masterson's attorney Thomas Mesereau asked Jennifer why reports of a gun were not included in a police report she filed the following year.
Mesereau also pointed out inconsistencies between Jennifer's 2004 police report and the 2003 "knowledge report" she filed with the church.
The alleged victim acknowledged that there were some differences, but said she tried to be truthful in both reports.
The preliminary hearing is expected to last four days.
As Masterson showed up to LA court on Tuesday, he posted a cheery selfie of his wife, Bijou Phillips, dropping him off.
"Had the most beautiful Uber driver drop me off at school today #uberwife #bijouphillips," he captioned the photo.
