No baby mama drama for Tom Brady -- the NFL superstar is on such great terms with his ex-GF Bridget Moynahan, he sent her a public birthday message!
"Happy birthday Bridget Moynahan," Brady posted Wednesday on his IG along with a 2018 photo of the actress with their son, Jack ... "We hope you have a great day."
Remember, Moynahan gave birth to Jack after they broke up back in 2006 -- a few months after Brady began dating Gisele.
