An insider told People that Bilson and the newborn are healthy and well. They have also asked the media to protect their privacy during this time. They have revealed their backing of the No Kids Policy, an initiative supported by several celebrities that would prevent paparazzi and others from snapping pictures of their children without their permission.

Bilson just wrapped the taping of Hart Of Dixie's fourth season. While her co-stars have not spoken out openly on the news yet, Jaime King revealed several times that she was ecstatic about the birth. King, who delivered her first child in October 2013, revealed that she was extremely "protective."

King and Bilson have similarities as they both filmed for The CW series while they were pregnant.

King told E! News Oct. 17, "She and I are very, very close. Rachel and my son have had a love affair from the very, very beginning since he first met her. Rachel has always been one of the most supportive people in my life in regards to my pregnancy.

People forget that she's growing a human being inside. I had to get IV fluids because it was so hot when I was shooting in Burbank, but I never wanted that to happen to her. I was always super, super, super protective of her and her child."

Hart Of Dixie returns to The CW Friday, Jan. 9 at 8/7c.
