Masterson has been charged with raping three women between 2001 and 2003 but has not been charged with sexually assaulting Jane Doe #4.
On cross-examination, Jane Doe #4 said about a month later, Masterson assaulted her again at her home.
Asked by Deputy District Attorney Reinhold Mueller what happened the next morning, Jane Doe #4 said "Danny was there."
Unlike the other accusers, Jane Doe #4 was not a Scientologist.
Dua Anjum reported from Los Angeles and Corky Siemaszko from New York City.
