The 43-year-old NFL quarterback posted a throwback photo of her with their 13-year-old son, Jack, on his Instagram Story on Wednesday to mark the special occasion. "Happy Birthday @bridgetmoynahan we hope you have a GREAT day," he wrote.
Brady and Moynahan are on good terms after their split in 2006 when the actress was pregnant with their son. Brady moved on with supermodel Gisele Bundchen that same year. Brady and Bundchen have been married since 2009 and share two kids -- Benjamin, 11, and Vivian, 8. Meanwhile, Moynahan married businessman Andrew Frankel in 2015.
"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 said at the time. "I don’t think you can ask for more than that. My son is surrounded by love."
"We all made the best of the situation and fortunately, he's the most amazing son," he said about his and Moynahan's child together. "My son, Jack, is like, my heart explodes when I think of him. He's the greatest kid I could ever ask for."
