Carrie's parents were the "It" couple in Hollywood of Eddie Fisher and Debbie Reynolds, before Eddie had an affair with Elizabeth Taylor and the marriage ended.
She was only married once for about a year to Paul Simon. It was a tough year for a variety of reasons but mostly because Carrie was bi-polar and had terrible bouts of depression. She medicated herself with drugs and alcohol in a horrible attempt to deal with it.
She did have a partner (Bryan Lourd), between 1991-1994 and they had a daughter named Billie. Dan Ackroyd proposed to her on the set of the Blue's Brothers movie but they never got married.
Although she was an actress in 41 movies (i.e. Star Wars, When Harry Met Sally, The Blue's Brothers, Shampoo, etc.), and many cameo appearances on TV shows, she was more comfortably as a writer having successfully written bestselling books, a play, a screenplay that turned into a movie, and she worked on many Hollywood scripts (i.e. Lethal Weapon, Sister Act, Coyote Ugly, Mr. and Mrs. Smith, three of the Star War's movies, etc.). I think she was a much better writer than most people knew.
Carrie said she lived with terrible demons and I'm amazed that she accomplished all she did with everything she had to deal with; it was because of this that she became a tremendous role model on how to turn your life around. I'll miss her!
