On Friday, Dec. 19 "Frozen" actress Kristen Bell and her husband Dax Shepard welcomed their second child and second baby girl together, Us Weekly reports.

The Hollywood couple, who are already the proud parents of almost 1-year-old baby girl Lincoln Shepard, took to Twitter to announce the arrival of Lincoln's baby sister and revealed the baby's name- Delta Bell Shepard.

Check out their tweets below.

A day prior to Delta's birth, Bell tweeted out that she had been "crying in the car" to Josh Groban's Christmas music and suggested that her tearful musical experience was an "early sign of labor."

E! News reports that during her pregnancy, Bell chose to keep the gender of her second child a secret from the public.

However, her husband, Shepard was quite vocal when it came to discussions on having more kids and expanding the family.

"We're building a circus," he said about growing his family during a recent appearance on "The Ellen DeGeneres Show." "Eventually, we want to get in a band and tour the country."

Bell and Shepard, who are also known for choosing unique baby names, previously admitted to People that they were having trouble finding a suitable name for their second child, but they eventually settled on one that could compete with Lincoln.

"We had a little bit of a breakthrough. We've settled on one [baby name], thankfully," Bell told People back in September. "It's a lot of pressure, especially because we felt 'Lincoln' was so perfect."

Although Bell's experience finding a name for her second child proved to be a difficult choice, the 34-year-old actress revealed to Us Weekly that both of her pregnancies were "really easy."

I've had a lot of friends who have had rough pregnancies and I'm really, really thankful," Bell added. "People are affected differently by hormones, we're all different."
