The pregnant star also shared a few behind the scenes snaps of the couple from the night, which was held to celebrate the premiere of WWE Friday Night SmackDown on Fox.
In one selfie, the pair sit side-by-side in the car on their way to the event, as Kazee appears to show off his best fighting face.
“Guess where we’re going again,” she wrote alongside the shot.
PEOPLE confirmed that Dewan and Kazee are expecting their first child together last month, with the couple telling PEOPLE exclusively, “We are beyond overjoyed and couldn’t be happier to be expanding our family!”
“Becoming a mother is quite simply the absolute best most incredible thing that has ever happened to me,” she captioned the cozy shot. “@stevekazee you are a gift from above and I couldn’t be more excited to be expanding our family together! Thank you guys for all the love!!”
Meanwhile, father-to-be Kazee called the moment something he has “waited my entire life for” as he praised his girlfriend of nearly two years for everything that she has brought into his life.
“Well … the news is out. I can’t even begin to describe the feelings that I have had since we first learned that Jenna was pregnant! I have waited my entire life for this moment and couldn’t have found a better person to build a family with,” he wrote alongside a photo of Dewan smiling and cradling her bump.
“Jenna also brought with her one of the greatest gifts one could ever imagine … her beautiful daughter,” he continued. “Evie burst into my life like a supernova and has continued to burn so brightly in it.”
“I have learned so much about parenting already from watching how amazing Jenna is with her and Evie has taught me so much about what it means to love and communicate with a child,” he went on, before sweetly adding, “I can’t wait to give her a sibling and make our little family a little bit bigger.”
