Jessica Biel has racy 'New Girl' guest spot

Jessica Biel is back on TV, and this is far from her '7th Heaven' role. She last appeared as Mary on '7th Heaven' in 2006 and as Jessica Rabbit on 'SNL' in 2009.

On the season premiere of 'New Girl,' Biel's sexy scientist character faced off with Jess for the affections of a hot best man at a wedding:

Kat: "That's me naked."
Jess: "Well... ...and this is me with a guy who I thought was Larry King. So it's decision time."
Kat: "Yeah, Ted, who's it going to be?"

Kat's scandalous pic just wasn't enough to win the best man over, though.

Ted couldn't decide between the two of them, and Kat ended up going home with the wedding's officiant instead.

Even though their characters butted heads on the show, Zooey Deschanel raved to Ellen Degeneres about working with Jessica before the episode premiered:

"She's so funny, so great. She's so nice and amazing."

"New Girl" fans even loved their collaboration.

As Vulture put it, "Admittedly, it's a story about two adult women in an adolescent catfight over a guy whose face is so bland he was basically a walking saltine, but Deschanel and Biel turned in hilarious performances."
