Throwback Thursday: Hollywood Edition

Before she stole our hearts as little Claudia Salinger on Party of Five, and long before gracing the big screen as Gretchen Wieners in Mean Girls, Lacey Chabert played a boy. On Broadway.

In fact, Chabert played Gavroche in Les Miserables on her 10th birthday because the boy actors were sick that day.

This gem leads the Throwback Thursday pack this week, which includes goodies from Julianne Hough, Nicole “Snooki” Polizzi, Jessica Biel and the boys from One Direction.
