The gorgeous couple recently welcomed their second son together, according to People.
Megan and Brian, who kept quiet for a couple of months about the news of their first child together, 16-month-old Noah Shannon, have yet to announce this baby news either.
The couple's latest addition to the family also joins Green's 11-year-old son Kassius, from a previous relationship with Vanessa Marcil.
In the midst of Megan's pregnancy this go round, Brian gushed over their son Noah, saying he hoped their son would welcome the new baby with open arms.
"I think that he's going to be a nurturer," the actor told the mag. "It's a lot to expect...I think he's going to be an amazing big brother with time."
Meanwhile, after delivering Noah, Megan was beaming when she talked about life as a new mom, with the 27-year-old Teenage Mutant Ninja Turtles star saying in March 2013, "All I wanted to do my whole, whole life was have a baby and now, I've finally done it."
"I just want to give Noah as much of myself as I can. And I want to have more kids. That's where my heart is at."
