In the vast, headline-grabbing world of celebrity biographers, Andrew Morton is king. Fittingly, he became a household name with his bestselling book about a princess, the late Diana. Since publishing 'Diana: Her True Story' in 1992, he's tackled Monica Lewinsky, Madonna and Tom Cruise -- all of them made the New York Times bestseller list and each was filled with scandalous nuggets about the stars. His latest tell-all, 'Angelina: An Unauthorized Biography,' is no different. I spoke with Morton about the real Angelina Jolie, her relationship with Brad Pitt and her kids, and whether he saw any Diana in the enigmatic actress.
