In one of her first photos of her bump since announcing the pregnancy in July, Cortese showed off her bump at 14 weeks pregnant.
"Excited to share our pregnancy journey with all of you!! Our first bump pic," she captioned the photo, assuring fans she wouldn't go overboard with baby bump photos. She and Buckner announced they were expecting in a Fourth of July-themed announcement in the beginning of July. A few days later, they shared a video of the gender reveal, sharing with fans they were expecting a boy.
Cortese posed in the same dress at 16 weeks pregnant to show just how much her bump was growing.
"[B]aby bump is growing.. he definitely popped in the last 2 weeks ..mommy and daddy can’t wait to meet you," Cortese wrote with a blue heart emoji. She added that the baby is as big as a dill pickle and that "Daddy is treating mommy like a princess even when she turns into a psychotic lunatic."
Cortese shared a photo a few weeks later wearing a "makeshift Snow White costume" before an event with Give Kids the World Village, a nonprofit resort for children with critical illnesses.
Her next official bump update came at 20 weeks, where she shared side-by-side photos of 20 weeks, 16 weeks and 14 weeks. She revealed that her first trimester was "rough" and that she "hit a little bump at the beginning of our second."
"I can’t believe we’re already half way there.. although the first trimester was rough and we hit a little bump at the beginning of our second.. this experience is amazing and I wouldn’t change it for the world and in a little more then 4 months it’ll all be well worth it ... Feeling him move everyday is an emotion I can’t even describe .. he’s already my best friend," Cortese wrote.
In her 24 week snapshot, Cortese shared that her and Buckner's baby is as big as an eggplant and added that she and Buckner were taking a "babymoon" before their bundle of joy arrives in a few months.
"24 weeks 5 days .. Baby is as big as an Eggplant .. Mommy is craving yogurt..peaches & Icecream .. and Mommy And Daddy are excited for our Baby Moon tomorrow !!!!" she wrote.
During their trip to the Bahamas, Cortese shared many mirror selfies at the Atlantis resort showing off her bump. In this one, Buckner stands behind her and holds her belly while they both smile for the caption.
