AT least one of the gals on “The O.C.” could be heading off into the sunset next year – following her high-school graduation in next week’s season finale.

Rumors have swirled for months that this will be the final episode for Mischa Barton, who is reportedly hoping to launch a career in films.

Meanwhile, a wily coyote is reported to have recently sneaked into Barton’s trailer on the set of “The O.C.” and polished off her dinner leftovers.

Production on one of the season’s final episodes screeched to a halt when the cast and crew heard Barton and co-star Rachel Bilson screaming and pointing in panic at the critter as it dined on the scraps.

Crew members allegedly lured the coyote out of the trailer and chased it away, back into the Malibu hills, according to a report in a London newspaper.
