AFTER HER PARENTS FORBID HER TO GO ON AN OVERNIGHT TRIP WITH ADAM TO ATTEND A CONCERT, JOAN GOES ANYWAY BY PRETENDING TO STAY AT GRACE'S, ON "JOAN OF ARCADIA," FRIDAY, FEB. 18

The Black Eyed Peas' Multi-Grammy Nominee will.i.am Guest Stars

Actress/Singer/Songwriter Haylie Duff ("Napolean Dynamite") Returns for Her Second of Three Consecutive Episodes

"Independence Day" -- Incensed that Will and Helen have forbidden her to go to a concert with Adam and stay overnight with him in his father's camper, Joan goes anyway, on JOAN OF ARCADIA, Friday, Feb. 18 (8:00-9:00 PM, ET/PT) on the CBS Television Network. James Hayman, one of the series' executive producers, directed the episode written by Ellie Herman & Stephen Nathan, the series' consulting producer and an executive producer, respectively.

The Black Eyed Peas' multi-Grammy nominee will.i.am guest stars as "Three Card Monte Guy God." Actress/singer/songwriter Haylie Duff ("Napolean Dynamite") returns as Stevie for her second of three consecutive episodes.

After Joan has a conversation with God about free will, she decides to use it as a rationale for lying to her mother in order to go on the trip as she's convinced that Helen simply wants her to remain a dependent little girl. Meanwhile, Luke is shocked when the nerdy, girl-obsessed Friedman rebuffs the advances of the surprisingly infatuated Stevie.
