JESSICA BIEL and Zooey Deschanel are going head-to-head in “New Girl.”

    Biel has signed on to guest in an upcoming episode of the Fox comedy — playing an obstacle in Jess’ (Deschanel) mission to get lucky at a wedding.

    The expanding loft gang — Damon Wayans Jr. is a regular this season — gathers for the last big event of wedding season and ups the ante by challenging one another to see who can get some at the nuptials. Newly single Jess sets her sights on a cute guest, only to have to vie for his attention with Kat (Biel). The character is described as “the hottest scientist in the world.”

    Best known for her film work of late, Biel is no stranger to TV. She starred in the first seven seasons of “7th Heaven.” She next appears in the movie “Shiva and May.”

    On the “New Girl” front, the story sounds in line with what creator Liz Meriwether told reporters earlier this week when talking about the decision to break up Jess and Nick (Jake Johnson).(SD-Agencies)
