Fox is about to make history by debuting its new comedy series on iTunes before it shows on TV.

In the debut episode of “New Girl,” Zooey Deschanel (“(500) Days of Summer”) stars as Jess Day, a young woman who, after discovering her long-term boyfriend is cheating on her, moves into a loft apartment with three male roommates – prickly bartender Nick (Jake Johnson), womanizer Schmidt (Max Greenfield) and intense personal trainer Coach (guest-star Damon Wayans, Jr.). The guys alongside Jess’ childhood best friend, Cece (Hannah Simone) try to help Jess get back on her feet and into the dating world.

The show can be downloaded on iTunes for free from today until the day of the series premiere, Tuesday, Sept. 20 (9:00-9:30 PM ET/PT).
