Prior to making her announcement — boyfriend Brick Stowell also posted a photo of her bump on his own Instagram — the actress, who plays Tara on the zombie drama, discreetly pointed out she’s been eating for two.

“Oh boy, do I love to eat,” she captioned an Instagram on Saturday, July 25, of a table full of steak and mashed potatoes, among other goodies. 

Oh boy, do I love to eat. ????
