In New Girl's newest episode, couple Jess (Zooey Deschanel) and Nick (Jake Johnson) are going to take a big step forward in their relationship as they move into together into Nick's room.

Hollywood Reporter says episode writer Camilla Blackett shares: "The difference between living with someone and really living with someone was a fine line that we were trying to walk"

"Even though these two people have lived together for two years, they've always had the safety of their own room. Throwing them in the same room, where they could see each other's weird stuff on a day-to-day basis, was such an eye-opening moment for the two of them," Camilla continues.

The move comes after Abby, Jess' sister who's shacking up with Schmidt (Max Greenfield), played by Linda Cardellini in her last guest appearance, motivates the couple to make the move.

"Jess is completely fueled with this competitiveness of wanting to prove that her relationship with Nick is so much better than Abby and Schmidt's," comments Blackett.

The episode titled, "Sister III" airs Tuesday, March 4, at 8/9 central on Fox. Watch the Episode Sneak Peek Here.  

In other news, taking a break from being "Jess," Zooey Deschanel, 34, hits up the Vanity Fair Oscars party in floral fashion. Donning a strapless Oscar de la Renta dress with ruffles, flowers and polka dots, Deschanel stayed true to her quirky, retro fashion sense.

Zooey's look had a very light and airy feel with the ruffles and soft pastel colors fitting for the usually low-key celebrity. The outfit was paired with a red purse, a bracelet, ring and light make up.
