Britt Robertson is no stranger to having to emote on the screen. She played a foster kid who finds her birth parents in the CW series Life Unexpected and a young waitress kidnapped and held hostage in CBS Under the Dome. The 27-year-old actress is now starring in the Netflix comedy Girlboss, based on the rags-to-riches story of Sophia Amoruso, who started selling vintage clothing on eBay in her early twenties and built the Nasty Gal empire that made her a millionaire.
