Kristen Stewart and Alicia Silverstone were the teen queens of their respective generations -- Stewart for playing the ingenue in the sparkly vampire series 'Twilight,' and Silverstone for her role as the, like, totally super cool Cher in 1995's 'Clueless.'

Tween sensation Stewart later broke free from her innocent on-screen persona by starring as Joan Jett in the film 'The Runaways,' getting nude for the Jack Kerouac-based 'On the Road,' and playing a badass Snow White in 'Snow White and the Huntsman' (which some saw as a fail because it asked viewers to believe Stewart was "fairer" than the stunning Charlize Theron).

After starring in the Jane Austen-inspired 'Clueless,' Silverstone went on to a few notables roles in flicks like 'Blast From the Past' and the widely-panned 'Batman & Robin.' In real-life, she feeds her son like a bird (literally) and has a rather unusual relationship with nature.
