After an involuntary hospitalization that was allegedly due to a drug problem, Mischa Barton is back on the set of her new fall series "The Beautiful Life." And, as executive producer Mike Kelley told E! Online, nothing is off limits when it comes to storylines for her character, Sonya.

He said, "I didn't want to be insensitive with what was happening with her. But at the same time I didn't want to not tell interesting and dramatic stories, and she was so game."

Mischa and Sonya have always had a little in common -- the character is a model whose rapid rise into the spotlight (i.e. Mischa on "The OC") is followed by scandal, struggles, and an attempt to regain her place at the top. Executive producer Karey Burke explained, "It's dealing with a character that is living her life in the spotlight, being hounded by the paparazzi, who is at a massive turning point in her career, where it's sort of make-it-or-break-it time, and there are things thematically where it's exactly what's going on with Mischa's life, and she's embracing all of them."

She's even embracing Sonya's possible drug use. Burke said, "Mischa's character ends up sort of taking a page from the whole Kate Moss situation and kind of using it to her advantage." Meanwhile, the writers are hoping for a crossover with fellow CW show "Gossip Girl," as they're both based in New York. Kelley told E! "My idea -- since these things happen -- there are blackouts. The idea is that we have two shows that exist in the same city, and if our cast is on the subway, and their cast is on the subway, and then the subway shuts down."

Great idea -- if a blackout hadn't already been the driving force behind "Gossip Girl" Season 2 episode, "The Dark Night."
