Leighton Meester is a Greenwich Gossip Girl

Leighton Meester (in Jill by Jill Stuart) totes around the Rebecca Minkoff “Nikki” bag while out and about with costar Nicole Fiscella in New York City’s Greenwich Village on Thursday.

The 22-year-old actress, who appeared in season one of Entourage as Justine Chapin, will reprise her role in season five, appearing in at least one episode in the first half of the season. Season five of Entourage is set to premiere in September.

Leighton is set to play a possible love interest for everyone’s favorite semi-successful actor Vince Chase (Adrian Grenier).
