She’s gearing up for a return to the set of her new show “The Beautiful Life” and  Mischa Barton is said to be ready for action.

According to her rep, the “O.C.” actress “will be resuming production as planned with the rest of the cast in NYC.  She’s back to business as usual.”
“The Beautiful Life” creator/producer Ashton Kutcher also commented on Barton’s status at a technology conference in Pasadena, saying, “I can tell you right now that Mischa Barton is doing great.”

Back on July 15th, Mischa checked herself into a hospital to deal with some personal issues, and has since overcome her problems enough to fulfill her work commitments.
