Moynahan and Brady discovered they were expecting a baby together after they had already split — and two months into the New England Patriots quarterback’s then-new relationship with supermodel Gisele Bündchen.
Moynahan gave birth to son John “Jack” Edward Thomas, now 12, in 2007, and while it hasn’t always been easy, the stars have worked to blend their families ever since.
“Tom and I made a decision to raise a child together and we both found partners that not only supported us in raising that child, but also loved our child as if he was their own,” Moynahan told PEOPLE in this week’s issue, on stands Friday. “I don’t think you can ask for more than that. My son is surrounded by love and grandparents that go on forever, and it’s all good.”
And while Bündchen admits that her boyfriend welcoming a son with an ex wasn’t an “ideal situation” at the time, she wouldn’t go back and change a thing.
“There’s no manual to prepare you for that,” Bündchen told PEOPLE in September 2018. “But I’m so grateful for [Bridget]. I know this was hard, but I couldn’t imagine my life without [Jack]. I call him my bonus child.”
“He opened my heart in ways I didn’t even know my heart could expand,” she added. “I fell in love with him.”
Moynahan has also expressed her gratitude for maintaining a stable relationship with Brady and Bündchen over the years.
“I have a relationship with these people on a daily basis. I’m raising a child, and it’s public,” she said in 2011. “My son has two loving parents and an extended family, whether it’s cousins or stepmothers or boyfriends.”
“I think from the very beginning the whole goal specifically was to always keep it positive,” Moynahan told PEOPLE of co-parenting. “To raise a son in the healthiest environment, and I know we’ve all done that, and it shows. I always encourage everyone to stay positive and understand you have to make the kids priority.”
Moynahan, meanwhile, married businessman Andrew Frankel in 2015, and together they raise Jack and his three sons from a previous relationship.
“[It’s] a lot of boys in the house,” she said. “There are just photographs and essays and letters all over the house, and they were very patient with the organized chaos that I had going on there.”
