Jack Nicholson once offered Princess Margaret cocaine at a dinner party held in her honour, a new book claims.
The actor is said to have pulled her aside at the glamorous event in Los Angeles and made the offer in an effort to get to know her better.
But the princess declined and spent much of the night drinking and dancing with John Travolta instead.
The anecdote is recounted in a new biography of top Hollywood agent Sue Mengers, who hosted the party for the princess in 1979.
The cream of Hollywood attended, including Sean Connery, Robin Williams and Barry Manilow. Nicholson turned up with his then-girlfriend, actress Anjelica Huston - but that did not stop him from approaching Princess Margaret who, in a black and silver Dior dress, was the focus of attention, author Brian Kellow claims in Can I Go Now? The Life of Sue Mengers, Hollywood's First Superagent.
