Claim to Fame: Party of Five
Chabert broke out as the loquacious child prodigy Claudia Salinger in Party of Five, though she’s more famous for trying to “make fetch happen” as the dimwitted Gretchen Wieners in Mean Girls. Although the 29-year-old hasn’t made a film as memorable since, Chabert has been assuming a steady stream of voice-over roles, most recently as Zatanna Zatara on the Cartoon Network series Young Justice.
