Although Bilson has yet to speak out about her pregnancy, her Hart of Dixie co-star Jaime King expressed her excitement about the upcoming pregnancy.

“I knew she wanted a baby,” said King. “She wanted it so badly.”

In fact, King, who has an 8-month-old son named James, has been giving Bilson pregnancy advice.

“[I told her] that she should drink a lot of water and stay out of the heat,” King told Us Weekly.
