Jamie Lynn Spears appeared in 2001's Total Britney Live and is in a Clorox and Pepsi commercial in 2002. She also starred in a number of commercials for Nickelodeon. In the same year, she appeared briefly in the movie Crossroads, as the younger version of the main character, Lucy, who was played by her older sister. For two seasons, Spears was a cast member on the Nickelodeon comedy-variety show All That. She played a number of different characters, including 84-year-old bodyguard Thelma Stump, who was the character that Spears portrayed in her audition for the program. She also did many On-Air Dares (a Nickelodeon version of Fear Factor) where she and other All That cast members had to do many "disgusting acts." She eventually left All That to star in Zoey 101, another Nickelodeon show aimed at the teen audience.
On Zoey 101, Spears portrayed Zoey Brooks, one of the first girls to pass admissions for a formerly all-boy boarding school called Pacific Coast Academy. Spears also sings the theme song for the show, entitled Follow Me, which was co-written by Emily Bob and Spears's sister, Britney. When the show debuted in January 2005, it drew a larger number of viewers aged 9-14 than any premiere on the network in the preceding eight years. Zoey 101 was nominated for a 2005 Emmy for Outstanding Children's Program. In 2006, Spears won a Nickelodeon Kids' Choice Awards blimp for Favorite TV actress.
DreamWorks Animation announced Jamie Lynn Spears portrayed Eva, Jim’s girlfriend in the live-action/animated version of Tom and Jerry.
