American actress Erika Christensen took to social media on Wednesday (29 June) to share the first photo of her newborn daughter. The Parenthood star and her cyclist husband Cole Maness welcomed their first child on 21 June. They have named her Shane.

The 33-year-old posted her daughter's photo on Instagram with the caption: "Week one down with the new BFF. Our girl Shane is killing the newborn game." The photo showed Christensen holding and kissing Shane, who is wrapped in a blanket.

According to People magazine, Christensen gave birth at her home in California. The newborn weighed 6lbs 3oz at birth, it reported. In March, Christensen had announced that she was pregnant by sharing a photo of herself with her pet on Instagram. She had captioned the photo: "This boy is getting a little sister. A human sister...She'll make her first appearance tomorrow at #Confirmation."

Meanwhile, Christensen told People magazine in April, "It's still rather surreal [being pregnant]. She's a little kick boxer in there – she's big and moving and communicating as far as reacting to music that we play and stuff like that."

Christensen then showed off her baby bump in a series of photos in Hawaii in May. The photos were shared by the actress on Instagram. One of the photos was captioned: "Kayaked to the island on the left, Moku Nui. So beautiful! ☀️ #Hawaii #8monthspregnant Bathing suit by @volcom."

The Swimfan actress before giving birth to her daughter informed her 163,000 followers on Twitter that she was in labour. She wrote: "I'm in labor. Right now."

The couple dated for three years before getting married in September 2015.
