Gisele Bundchen and Tom Brady Sweet Pictures

Four years ago today, Gisele Bündchen and Tom Brady married in Costa Rica! The past 48 months have been good to the couple. They expanded their family with the December 2009 birth of their son Benjamin Brady, and again last December with the arrival of Vivian Lake Brady. The Brady-Bündchen clan has put down roots in both LA and Boston, where Tom plays for the New England Patriots. He got an early anniversary present this week by extending his contract with the Patriots through 2017.
