Bella posted a slideshow of photos of the pair on Instagram, the first a snap of herself sitting on Chigvintsev's lap as he placed his hand on her stomach. The rest of the photos were taken on the same day and saw the couple walking down the street together, Chigvintsev's arms around Bella's waist as he hugged her.

"Baby Daddy," Bella's caption read along with a red heart emoji.

On Thursday, the former WWE star shared a photo from the couple's afternoon together of Chigvintsev holding an envelope in his hand, which Bella dubbed "our baby's golden gender reveal ticket!!"

Early Friday morning, she used her Story to give fans a look at her baby bump, noting, "Still some abs, but my bump is getting bigger!"

"How cute," she added. "It's like right here at the bottom. I love it... It's so crazy to watch it grow."

I was definitely shocked when I found out. And so nervous! I wasn't expecting it and felt I wasn't ready but this journey of life is unpredictable.
