Portia de Rossi has accused Steven Seagal of sexually harassing her during an audition.

She claims the actor unzipped his trousers in front of her and sexually propositioned her.

She wrote on Twitter: "My final audition for a Steven Segal movie took place in his office.

"He told me how important it was to have chemistry off-screen as he sat me down and unzipped his leather pants.

Her wife, talkshow host Ellen DeGeneres wrote: "I’m proud of my wife."

A representative for Steven Seagal has been contacted for comment.

The actress is just one woman who has accused Seagal of sexual misconduct.

Last week, Julianna Margulies said she was sexually harassed by the actor, who intimidated her by showing her his gun in a hotel room.
