An actress for her entire life, Kimberly McCullough has truly become synonymous with her "General Hospital" character Robin Scorpio. She made her screen debut at just seven months old, in a diaper commercial, and by four had graduated to dance, which in turn led to her big-screen debut, seminal 1980s dance flick "Breakin' 2: Electric Boogaloo," at the age of five. The following year she auditioned--a whopping 12 times--to win the role of six-year old Robin Scorpio. Her performance was a huge success for the show, and by the time she was 11 she'd won her first Daytime Emmy. Her most famous story arc came in the mid-'90s, when her character learned that she had become infected with HIV after having unprotected sex; Scorpio has the distinction of being the only daytime TV character living with the virus. McCullough soon began to study at New York University, while returning on her breaks to play Scorpio. While dabbling in feature films, including the hit law-school comedy "Legally Blonde," she also started to take parts on primetime dramas, such as the family-oriented "Once and Again" and the religious-themed "Joan of Arcadia." Both of these series sputtered out after one season, but McCullough was still portraying Scorpio sporadically, and in 2005 decided to return to the show full-time; her character had now graduated form medical school and was a practicing doctor, who played a key part on the one-season primetime spin-off "General Hospital: Night Shift."
