She claims Pardue became aroused while they were under a bedsheet waiting for the scene to begin.
“I clearly misread the situation during a sex scene on set and have apologised to Sarah,” he said in a statement.
Scott, who has appeared in TV shows including True Blood and Castle, alleges that the incident involving Pardue happened on 16 May when they filmed a post-coital scene together for a pilot series called Mogulettes.
Scott says she later asked Pardue, 43, why he did what she alleges him to have done.
