While on One Life to Live, she appeared on the Oprah Winfrey Show as one of daytime's most popular characters. She was a series regular on Baywatch, and has had recurring roles on several television series including Pacific Blue, Middle Ages, and as a young teen on House Calls opposite Lynn Redgrave. She has been seen on television shows including Scandal, Private Practice, House, Perception, Friends (as one of Joey's famous sisters), ER, Dream On, and Ringer to name a few.
