Once her contract ended, she continued on to star in movies such as The Perfect Holiday and Major Movie Star. Additionally, she appeared in American Horror Story as well.
Christina Aguilera
You probably know who Christina Aguilera is. The Mickey Mouse Club alumnus has definitely made a name for herself over the years. Nowadays, the talented singer is a judge on the TV show The Voice. However, before she became her famous self, she was on the cheerleading squad in her middle school in Pennsylvania. Still, her time on the squad was rather short since she quit the squad in order to pursue singing. Clearly, she made the right decision.
