Christina was born in Santa Monica, California, on February 12, 1980. Sometime later her parents moved to Montclair, New Jersey. Later on, while in a school play, one of the mothers in the audiance saw Christina and thought that she was very good, so she told Christina's parents that she basically had a lot of talent, and the mother told them to go see an agent that she knew. A short time after Christina was in a movie with Winona Ryder and Cher, called Mermaids. It was the very first movie that Chris was ever in. Sometime around 1995 Christina's parents got a devorce and it was very hard on Christina and, partially because of this, Christina became anorexic and she was like that for about a year, until she herself finally pulled herself out of it and got some help. Christina and her mom moved to Manhatten sometime after, where Christina attended Manhatten's Professional Childrens School, with fellow class mate and actor Macauley Culkin. Christina and her mom are now both astranged from her father.
