Jaime King posted a picture of the cast of the hit series on Instagram Sept. 20 including Bilson, Scott Porter who plays George Tucker and Wilson Bethel, Cress Williams (Lavon Hayes), Kaitlyn Black (AnnaBeth) and Wilson Bethel who portrays the infamous Wade Kinsella.

King included the caption, "My beloved cast. My family. I love you all in ways greater than I could ever express. Everyday each one of you inspires me and brings magic to my life with every action, cut and in between."

'Zoe 2.0' Set To Come Shake Things Up On 'Hart Of Dixie'

Bilson holds her abby bump in the snapshot while rocking a black and white striped cardigan, an all black outfit and sandals. Bethel's hands rest on her shoulders. Fans have been waiting to see or hear news of Bilson's character Zoe Hart possibly being pregnant in the series. If she is, it will be interesting to see who fathers the baby. She and Wade have gone back and forth since season one. But she professed her love for him on the season three finale and he has yet to respond if he still feels the same; or whether he wants to go back down that route.

As for Zoe and King's character Lemon Breeland, they seemed to have buried their ongoing feud on the season finale as well. After both being single for the first time at the same time, they had a girlfriend moment and went as far as confiding into one another on their love lives. It looks like Lemon and George could rekindle their romance that Zoe broke up in the debut season.

Hart of Dixie returns to The CW in early 2015. It has not been given a premiere date. Be sure to keep up with Enstars for spoilers and cast updates.
