Kristen Bell's baby girl Lincoln is going to be an older sister very soon! The 'Frozen' star and husband Dax Shepard are expecting their second child together!

Bell and Shephard are already the parents to a 13-month-old baby girl Lincoln. They have been married since October 2013.

"Kristen and Dax are expecting their second child and a sibling for Lincoln," a spokesperson for the couple confirmed to ET. "The whole family is beyond excited."

Bell was most recently seen at the American Express Epic EveryDay Getaway with Soul Cycle in New York City on Friday. The actress isn't showing a baby bump yet, but she did chat with People magazine about her fitness routine.

"My go-to workout is usually hiking," Bell said to PEOPLE. "[Hiking] is easy because sometimes it doesn't actually take me away from anything because my whole family's coming on the hike."

"I often will strap the baby to my chest for the hike," she added.

"She's delicious. It's such a fun age," Bell said about her daughter. "I feel like having a toddler is exhausting and extremely rewarding - and far more rewarding than exhausting."

Bell recently spoke with Glamour about her and husband Shephard's stand against allowing magazines to print photos of celebrities' children.

"I signed up to be an actor, and I understand there are consequences," she said, "My daughter, on the other hand, should not have to accept that lifestyle because of the choices I made. There's a very big difference between a mother taking a photo of her baby and a kid coming out of school followed by 10 strange men with cameras. A child can't comprehend the media machine; she feels hunted."

After meeting with numerous editors and executives, Bell has convinced more than 60 media outlets to take the No Kids Policy pledge, including People, Us Weekly, Access Hollywood, and Glamour.
