Zooey Deschanel certainly knows how to keep a secret.

At the New York City premiere of Rock the Kasbah, the New Girl star and her husband, Jacob Pechenik, finally revealed the name of their 3-month-old daughter. The quirky couple (below) told People that they named their little one Elsie Otter.

"It's Elsie," Deschanel began, while Pechenik added, "Otter." "Like the animal," the 35-year-old actress explained.

People confirmed the couple's marriage alongside the birth of their first child in August, and the new parents have kept their new girl's name under wraps until now. Tuesday night's premiere also marked Deschanel's first red carpet appearance since having a baby and for it she donned a sparkly dark gray sheath dress with polka-dot tights and pointed-toe heels:

Although we've yet to see a single photo of Elsie, Deschanel's New Girl costar Lamorne Morris told People last month that she's extremely cute. "She looks like Zooey," the actor added.

Teenage Mutant Ninja Turtles star Megan Fox will take over Deschanel's main role in Fox's hit comedy series New Girl for a portion of its fifth season while she enjoys the remainder of her maternity leave.
