Amanda Laura Bynes was born on April 3, 1986 in Thousand Oaks, California. The youngest of three children, she became interested in acting and performing from the very young age of three, when she would say her older sister Jillian's lines with her while she performed in plays. It was from then on that her family and friends knew that she would be a star some day.
Her acting debut was in 1996 when she auditioned for and got the role as a newcomer on All That. Right away, she became very popular as people enjoyed her acting and skits, especially the "Ask Ashley" skit where she played a little girl running an advice column who would get very angry every time she read a letter.
In 1999, thirteen-year-old Amanda was given her own variety show, The Amanda Show, in which she starred in all of the skits except "Totally Kyle".
In 2001, she co-starred with Frankie Muniz in Big Fat Liar as Kaylee, Jason's friend who helps him prove that he really did write the essay "Big Fat Liar" and regain his father's trust. It was also in 2001 that she began dating Taran Killam, from The Amanda Show and Big Fat Liar, who is four years and two days older than she is. She also won a Nickelodeon Kids' Choice Award and, at age fifteen, ended The Amanda Show.

A week before its finale, Amanda made a return to the big screen when She's The Man opened in cinemas.
