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.
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.
