Actress Charlene Tilton has slammed her former Dallas co-star VICTORIA PRINCIPAL as a "real bitch". Tilton claims Principal cut all ties with the cast and crew of the hit TV show as soon as it finished shooting in 1991. But the 47-year-old, who starred as LUCY EWING, still values the friendship of Larry Hagman. She says, "Victoria Principal didn't want to have anything to do with any of us after we'd finished shooting. She is a real bitch. "Larry is a great person. He has become a father to me and has always given me valuable tips and great advice. I can always call him, he always has an answer. "I don't see the others anymore really - I see some at parties sometimes, but there's never more than a short hello. "Patrick Duffy lives a very secluded life. After the murder of his parents, he stays in the country and comes to LA very rarely."
