Actress KATIE CASSIDY was left red-faced when she auditioned for the role of LUCY EWING in the upcoming Dallas movie - because she dressed for the part. The pretty blonde daughter of pop icon David Cassidy felt she'd have the best chance of landing the dream role if she showed director Gurinder Chadha what she'd look like as busty Ewing - but she just found her efforts hilarious. She recalls, "I had this big Texas hair, jeans, cowboy boots, and a yellow tank top that I stuffed to give myself a bigger bust. "The director said, 'I can't believe they told you to dress like Lucy.' I was so embarrassed."
