The 34-year-old actress is expecting her first child with husband James Heerdegen, according to People.
The mom-to-be’s pregnancy was revealed as she made her way through Los Angeles International Airport in a belted black dress with Heerdegen on Saturday.
Ricci met Heerdegen, a camera technician, on the set of her former show "Pan Am," and then wed in October of 2013 at Manhattan’s Harold Pratt House & Peterson Hall.
"Getting to say 'fiancé' instead of 'boyfriend,' " is the engaged actress's favorite thing about her relationship status, she tells PEOPLE at Sunday's Citi-sponsored Smurfs 2 premiere in N.Y.C. "People take you so much more seriously once you start throwing around that word."
“I can’t wait [to call him], ‘Husband'" because then I can really throw my weight around,” Ricci told People in July of 2013.
The couple tied the knot in October 2013 in an intimate ceremony in New York City at Manhattan's Harold Pratt House & Peterson Hall.
"I'm excited to be with all my friends and family and just have a lovely night," she had said of her nuptials. "I love so many things about [James]. He's my favorite person on Earth.
Ricci has been acting since a child in the 1980's and has appeared in a number of darker films over the years. She has taken to roles that transformed her from a child star into a sought after actress playing pivotal inspiring roles since the 90's.
By the late 1990s, Ricci had become one of the most in-demand young actresses in Hollywood. In 1999, she starred in the indie flicks 200 Cigarettes and Desert Blue with Casey Affleck and Kate Hudson. She also took on the role of the Gothic princess Katrina Van Tassel opposite Johnny Depp's Ichabod Crane in Tim Burton's adaptation of Sleepy Hollow.
Ricci continued her trend of playing more melancholy roles with her portrayal of Lizzie Borden in the Lifetime TV movie Lizzie Borden Took An Ax (2014).
