BOSTON – A former fashion model and actress says Bill Cosby made sexual advances and lewd gestures toward her on the set of "The Cosby Show."

Helen Gumpel, formerly known as Helen Selby, says Cosby had her sit on a couch in his dressing room, where he handed her a drink then stood in front of her with his crotch in her face.

Gumpel held a news conference in Boston on Sunday. A Cosby spokesman didn't immediately respond to a message seeking comment.

The 77-year-old entertainer faces sexual assault accusations from at least 15 women. He has denied the allegations and has never been charged with a crime.

Also Sunday, Cosby canceled back-to-back comedy shows at the Wilbur Theater where demonstrators threatened to rally. He told the Boston Globe he canceled because of impending "treacherous" weather.
