The couple, who got married in March 2010, have two daughters: Olive, 6, and Elula, 4.
If her past pregnancies are anything to go off of, Fisher has plenty of carbs in her future. In an interview after giving birth to Elula, Fisher told Fitness magazine that her morning sickness dictated her meals.
"I had severe morning sickness both times, so I mostly ate supersize bowls of white pasta with loads of butter and cheese because that was the only thing that took away the nausea," she said.
In an interview with the Telegraph last year, Fisher said that her family impacted what roles she chooses to take on.
"Family is 100 percent my top priority," she said. "So I’m much more comfortable doing supporting roles right now. And often they’re the most interesting. You get to be a character actress."
Cohen's upcoming projects include the sequel to Tim Burton's "Alice in Wonderland" and "Grimsby."
