Jacqueline MacInnes Wood
Wood made a name for herself playing the part of the "hair girl" on a commercial for First Choice Haircutters. At the age of 18, she moved to Toronto to pursue a career in acting. In May 2008, she began playing the contract role of Steffy Forrester on the American CBS Daytime soap opera "The Bold and the Beautiful". Since Wood stepped into the role, Steffy has been noted as being a "bitch-nasty" vixen who is strong willed. Of playing her, Wood said in 2011, "I love playing her and developing her character. She is so different from me. It's rather cathartic, and it allows my alter ego to come out on "The Bold and The Beautiful" set five days a week."
