Kaley was both an athletic and theatrical prodigy; she first appeared in front of the camera at only 8 months old and, by age 3, she was playing tennis, which was her first career aspiration. At 6, Kaley began modeling and took roles in Los Angeles-area stage productions of Annie and Fiddler on the Roof.

She later portrayed Maureen McCormick (a.k.a Maria Brady) in the television film Growing Up Brady.

In television movies, Cuoco's credits include Crimes of Fashion, 10.5, Alley Cats Strike, Toothless, Attack of the 50ft Woman and Dean Koontz's Mr. Murder.
Cuoco often lends her voice to animated television shows, including You Can Hear Her, Brandy and Mr. Whiskers, where she plays Brandy, the snobbish dog, and Bratz, a show based on the best-selling dolls.
Cuoco recently wrapped production on the independent film Farewell Bender, a story about a group of high school friends who reunite in their hometown for the funeral of an old buddy, Bender, and spend a weekend struggling to accept that Bender escaped what they can't - adulthood.

Kaley Cuoco, known for her role as the late John Ritter's daughter on 8 Simple Rules, joins the cast of Charmed in its eighth season as Billie, a young witch under the guidance of the Charmed Ones.
Billie Jenkins was introduced, in the show's eighth season, as a young witch who pays more attention to demon fighting than to her education. Billie was put under the tutelage of the Charmed Ones after she asked them to teach her everything they know about witchcraft. This, at the time when the Charmed Ones were thought to be dead, proved useful for the three sisters, as Billie could carry out smaller magic-related tasks and also to cover for them.
Billie's backstory involves the abduction of her sister, Christy Jenkins, by mysterious demons with unknown intentions. This -- along with the fact that the incident was never mentioned by her parents, leaving Billie even more confused -- was the main motivation for Billie to train and become skilled in using her powers. Her main objective was to find out who kidnapped Christy and why, and to save her if she is still alive. Upon meeting with an Angel of Destiny, Billie was assured that her sister is alive and she will eventually find her. Her sister was revealed to be kidnapped by a suprisingly alive Triad because she is the key to "ultimate power".
