Jen Aniston -- Dinner or Date?

9/3/2010 8:57 PM PDT BY TMZ STAFF
Studies have shown ... workplace romances have a pretty high success rate -- so maybe that's why Jennifer Aniston went on a dinner date with her "Cougar Town" co-star Josh Hopkins last night.

Aniston -- who will be guest starring on "Cougar Town" this season -- was photographed riding shotgun in Hopkins' ride after a romantic chow-fest at Madeo in Hollywood.

Of course, Jen was also reportedly spotted at a one-on-one dinner with Lindsay Lohan's ex-BF Harry Morton earlier this week. So, the question is ... is Jen hungry for a man ... or just hungry?
