The couple begun dating in mid-2014 after they met on the set of Rock the Kasbah, which Pechenik co-produced.
Deschanel recently confirmed the couple's exciting news to PEOPLE.com, saying, "Jacob and I are over the moon. We are so excited to meet our little one."
We're over the moon, too! And how fun is it that Zooey's sister (and star of Bones), Emily Deschanel, is also pregnant at the same time? Emily is expecting her second child with husband and It's Always Sunny in Philadelphia star, David Hornsby, later this year, and is already mama to a 3-year-old son named Henry. Talk about a ready source of pregnancy advice and mom-advice—not to mention a sympathetic ear when it comes to morning sickness (if she's having any), weird pregnancy symptoms, and kooky cravings.
Now, we can only hope a She & Him lullaby album is also in Zooey's future...
Congrats to Zooey (and Emily, too)!
