Mischa Barton Joins 'Dancing With The Stars'

A decade after Mischa Barton's most famous character, Marissa Cooper, died on "The O.C.," Coop is coming back to life to dance.

Barton will compete in the 22nd season of "Dancing With the Stars." Jodie Sweetin from "Fuller House" is also set to compete. (Actually, Barton knows a thing or two about over-filling houses herself: One time on "The O.C.," her character snuck a crush into her mom's unfinished house, which led to a series of events that burned the whole place down. Perhaps by the end of the "DWTS" season, we'll know who can achieve the "Fullest House.")
