The `Tron: Legacy` actress - whose mum, Leslie Cockburn, is a producer on CBS news show `60 Minutes`- explained her mother was instrumental in teaching her the art of being "sexy and attractive" but also "the smartest person in the room". She said: "My mum taught me a lot. Especially about how, as a woman, you can be sexy and attractive and yet still be the smartest person in the room." However, Olivia`s mother is not the only person to have an impact on her life. The 27-year-old beauty admitted `House` co-star Hugh Laurie taught her how to be aware of "little things" when she is portraying certain roles. Olivia added to Culture magazine: "Hugh taught me how, as an actor, you need to be aware of little things, like how people usually look upwards when entering a room. "Hugh is hilarious and arguably one of the best actors working today. I think I have learnt more from him in the past four years than I have from anybody else."
