Bundchen gave birth to daughter Vivian Lake last Wednesday (December 5) and later shared the first image of the baby on Twitter.
New England Patriots quarterback Brady has now commented that both he and Bundchen are overjoyed to have welcomed their bundle of joy.
"It feels good," Brady declared to The Boston Herald, adding: "Whatever we would have had, I would have been happy. We've got two beautiful boys, now a girl. It's great."
Brady also joked that he already expects Vivian to follow in his footsteps in the sports world.
"She's going to be an athlete," he teased.
Bundchen and Brady are already parents to son Benjamin Rein Brady. The couple wed in February 2009 in Santa Monica, CA.
Brady also has a son called John Edward Thomas Moynahan with ex-partner Bridget Moynahan.
