5. Jessica Capshaw & Steven Spielberg
Grey's Anatomy star, Jessica Capshaw is not only the daughter of Kate Capshaw, best known for her role in the 1984 film, Indiana Jones and the Temple of Doom, but also the step-daughter of prolific movie director, Steven Spielberg. Jessica is best known for her role as Arizona Robbins, a pediatric surgeon in medical drama Grey's Anatomy and was 15 years old when her mum married the Jaws director. In recent interviews Jessica has stated that coming from a showbiz family actually made things more difficult for her to get into the business and has said ''Well, when you come from all that, who wants to see that girl succeed. You want to see the underdog succeed, the girl who spent her last two dollars on the bus ticket." But we think having Steven Spielberg as a step-father probably served as a bit of a helping hand!
