According to Anjelica Huston, her relationship with Ryan O'Neal nearly 40 years ago was more volatile than anyone ever realized.

In her upcoming book Watch Me: A Memoir, the now 63-year-old Oscar winner and member of one of Hollywood's most famed acting and filmmaking dynasties writes that her then live-in boyfriend assaulted her during a party at a Beverly Hills mansion in the late 1970s.

"He turned on me, grabbed me by the hair and hit me in the forehead with the top of his skull," she writes in an excerpt from the autobiography, which is due out next spring. "I saw stars and reeled back. Half blind I ran away from him."
