A Hollywood exec has told how she was sexually harassed by Steven Seagal as a budding actress on the set of his 1991 movie “Out for Justice.”

The exec, who asked not to be named for fear of repercussions, said Seagal lured her to his trailer for a “costume change,” then propositioned her by phone, crudely demanding, “You are not comfortable sitting on my face for an hour?”

She alleges that her first day on the set, Seagal insisted that all the new actresses gather for him to “check us all out.”

The former actress said, “Moments later, a wardrobe assistant led me to Steven’s personal trailer, to his bedroom, and asked me to change into a corset. Then, Steven opened the door [and] tried to barge in. I said, ‘Excuse me, I am changing in here,’ but he insisted, ‘I need to see what you look like.’ I told him that I wasn’t comfortable and began screaming for the wardrobe person. He just smirked and said, ‘It’s OK, I like nice girls, too.’ ”

The next night, Seagal — who was married to Kelly LeBrock, who’d just given birth to their second child — called the woman at home, saying Gregg Allman had recorded music for the soundtrack. “Steven told me, ‘You should come by and listen to some of the tracks. I’m staying at the [Hotel Bel-Air].’”

Again, she said she didn’t feel comfortable, and alleges that Seagal responded, “You are not comfortable about coming over and sitting on my face for an hour?’”

The ex-actress said, “I told him, ‘You’re married,’ and he just said, ‘Ah, you are no fun.’ I worked for two weeks, then they let me go. If I’d gone to the hotel room and slept with him I would have had a much better role.”

She recounted the ordeal to a fellow actress on the movie, who wasn’t surprised, “ ‘He didn’t give you a pager?’ she asked. ‘He has given them to a few actresses, and when he pages, you have to go immediately to his hotel room, even if it is 3 a.m.’”

Jenny McCarthy, Portia de Rossi and Julianna Margulies have also accused Seagal of inappropriate behavior.

His rep didn’t get back to us.
