The actress posted a throwback photo from the set of Hart of Dixie on Monday – and put rumors surrounding the show's cancellation to rest.
"Just wanted to clear something up, the cancelation of HOD had nothing to do with me or my pregnancy," she captioned a behind-the-scenes Instagram shot. "I loved my show and loved playing Zoe Hart, thanks to everyone who watched."
Bilson, 33, and longtime love Hayden Christensen welcomed their first child, daughter Briar Rose, last October.
The CW pulled the plug on the medical comedy after its fourth season in May. Bilson's character, Dr. Zoe Barnes, had a baby in the series finale – plus, costar Jaime King, who played debutante Lemon Breeland, gave birth to son Leo Thames on July 16.
"I tell her everything because she and I are very, very close. Rachel and my son [James Knight, 22 months] have had a love affair from the very, very beginning since he first met her," King, 36, told E! News last year of giving Bilson parenting tips. "Rachel has always been one of the most supportive people in my life in regards to my pregnancy."
