Gossip Girl's Leighton Meester is heading to Los Angeles. According to E!, the actress is set to reprise her guest-starring role on Entourage. Back in season one, Meester played pop singer Justine Chapin in the episodes "The Review" and "Date Night." The character was modeled after a pre-tailspin Britney Spears--a self-professed virgin who happened to have a thing for Vince (Adrian Grenier).

Meester will appear in at least one episode in the first half of the season. Production of season five of Entourage began in April, with a premiere set for September. The show was supposed to return in June, but was delayed by the writers' strike.
