Isla Fisher pregnant

Isla Fisher has finally admitted to being pregnant. Sacha Baron Cohen's fiancé says she plans on taking some time off for her next big project: the birth of her first child reports PEOPLE

"I haven't got any plans to jump back into [work after the birth]," Fisher told reporters at a recent Los Angeles press event for her new movie, Hot Rod.

Due in winter, Fisher, 31, said she has not found out the baby's gender, nor has she decided whether she'll give birth in London or L.A., where she and Cohen split their time.

"I'm so happy, very happy, and very excited."

The actress – and two-time novelist – won't be writing again anytime soon, either: "I plan on just coloring in books. I'll focus on that for the next few years," she said.
