ROLE MODEL

By 2002, Jamie Lynn was testing stardom herself. She appeared in Crossroads – her sister's unsuccessful foray into movies – as a younger version of Britney's character, Lucy. "She's the little star at school right now," Britney told PEOPLE at the time. "She's just 'Miss Everything' and lovin' every minute of it." The fresh-faced Jamie Lynn also walked the runway as a model for Kids R Us.
