Lyndsy Fonseca and Noah Bean have gone from co-stars to co-parents.

Nearly five years after starring in The CW's "Nikita" together, the two actors are taking on another big adventure. Fonseca gave birth to their first child, a little girl, on Feb. 2. She introduced their daughter to the world on Thursday, revealing that they named her Greta Lilia Bean. The baby weighed 7 pounds, 12 ounces and measured in at 20.25 inches long.

"Our hearts are bursting," Fonseca wrote in her Instagram post, which featured three photos of Greta.

They got married in October 2016, and based on the hashtag the actress used in her Instagram post, she has been wanting to have kids for quite some time. We're happy for the couple and their adorable new daughter!
