Isla Fisher plans on taking some time off for her next big project: the birth of her first child with her fiancé, Borat funnyman Sacha Baron Cohen.
"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, which hits theaters next Friday.
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," gushed the actress best known for her role as a zany sister-of-the-bride in Wedding Crashers.
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.
Her Hot Rod costar, Saturday Night Live's Andy Samberg, says Fisher will be a good mom. "Yeah, I think so," he told PEOPLE. "That's gonna be an interesting family. That kid has got to brace himself. That kid's got something in for him."
Asked if the child would be a born comedian, because of his parents, Samberg cracked: "Or it will just reject comedy altogether, because there's no living up to [them.]"
