"Beautiful announcement! Congratulations to all 3 of you."

"IM SO HAPPY This is the best news because she is so perfect and has the most perfect family and I just want her to be my best friend."

Another wrote, "awwww I love this cute announcement! Congratulations."

Fans of King know this is major news because King has been extremely candid and open in her struggle with fertility before she gave birth to her first child, James Knight Newman, in October of 2013. She has revealed to her fans that she suffered several miscarriages before James' arrival, so a second pregnancy for her is pretty amazing! King currently stars in The CW's hit show Hart of Dixie. When she was pregnant with James, she filmed all the way before she gave birth before taking a six week leave.
