This will be Green's fifth child and Burgess' first child. With his ex-wife Megan Fox, the 48-year old actor has three children -- Journey, 5, Bodhi 7, and Noah, 9, respectively -- Kassius, 19-year-old, is his father with Vanessa Marcil.
Green smiles happily as he places his hand on Burgess in one photo. As she takes in the love, the mom-to be is radiant in a white bikini top.
Others photos capture the couple strolling on the beach, sharing a sweet kiss and another photo shows Burgess, 36 laughing as Green holds him.
Burgess also took a single shot giving fans a complete look at her baby bump in a white bikini.
ET spoke to the couple last June and Burgess shared her hopes for motherhood when she was interviewed by ET.
She said, "Kids were always on the cards for us," "One hundred percent, they have always been on my cards. We'll just have to wait and see what the universe has in store. We will leave it open."
Burgess enjoyed spending time with Green's kids in the meantime.
"I love spending time in the company of my boys. They are a joy to have in my life. She said that they are amazing children, so it is not difficult. "... "They're amazing little people. It's all about becoming friends with them, learning their interests, playing with them, and having fun. They are truly amazing."
Green was praised by the dancer and actor for being "an amazing father" as well as his kind words for Green's girlfriend.
She's great with them. She is super playful. He said that they enjoy spending time together and have a great relationship. She's also intuitively able to be a stepparent but still bond with them and love. They feel very safe with her and it's an incredible connection.
In October, DWTS partners celebrated the one-year anniversary with the actor exclaiming, "I've never loved before #damnimlucky."
"One year ago yesterday, my entire world changed. It was just that I didn't realize it yet. Burgess shared the following Instagram message: "You're everything I ever wanted in one person, and the way that you love me is something that I couldn't have even imagined," Burgess wrote. It was something I didn't know existed until I met you. You are my baby and I love sharing my life with you. All of them are to go, 1 down. :)."
The happy news about Green and Burgess comes just days after Fox's engagement with Machine Gun Kelly. ET was informed by a source that Fox "couldn’t care less" after Green's ex-wife made the announcement with her fiance.
"He doesn’t feel any romantic feelings for Megan, nor any anger. The source stated that Brian is happy for Megan, but that it isn't affecting him in any way. "There is no bad blood between them. He is mainly indifferent to Fox's engagement and just happy that they are co-parenting well together.
