The Parenthood star, 33, who gave birth to her bundle of joy Tuesday, June 21, debuted her little girl via Instagram Wednesday, June 29, in a shot that showed the adorable tot swaddled in a white blanket with stars with her mom giving her a heartfelt kiss on the cheek.

Christensen, who appears to be wearing very little in the photo, looked totally blissed out as she cradled her tiny baby's head in her hands, evidently enjoying every moment of being a new mom.

"Week one down with the new BFF. Our girl Shane is killing the newborn game," she captioned the photograph proudly.

Christensen and her husband, Cole Maness, are notoriously private and kept news of her pregnancy under wraps until she appeared on the red carpet for her new movie, Confirmation, in March, showcasing a visible baby bump.

Their baby — whose arrival was marked by a Twitter announcement from the new mom that said "I'm in labor. Right now" — came into the world weighing 6 pounds, 3 ounces.

The actress married her cyclist husband in September 2015.
