New England quarterback Tom Brady's newborn son has the initials JET.
"Bridget is very thankful for a happy baby, excited about being a mother, and very pleased that the father, Tom Brady, was able to be there for the birth," publicist Gary Mantoosh told The Associated Press.
Moynahan and Brady split up late last year after a three-year relationship. Brady has been dating supermodel Gisele Bundchen.
Brady, 30, has led the Patriots to three NFL titles and is a two-time Super Bowl MVP. New England opens its regular season against the rival New York Jets on Sept. 9.
Mantoosh didn't give any other details, including the size of the baby or whether Thomas was in honor of his father.
"Both mother and baby are at home, happy and healthy," he said.
Brady flew to California for the birth and returned to his team a few days later for a preseason game.
Moynahan, 36, is a former model who has starred in films and television shows.
