Tom Brady, thrower of footballs, and his wife, Gisele Bundchen, walker of runways, have announced the birth of their second child, a teensy-weensy little girl named Vivian Lake who, if her genes tell us anything, should be winning schoolyard football games and fashion contests before she reaches the age of 10.

Bundchen took to Facebook to trumpet Vivian's arrival.

"We feel so lucky," she wrote "to have been able to experience the miracle of birth once again and are forever grateful for the opportunity to be the parents of another little angel. Vivian Lake was born at home on December 5. She is healthy and full of life.Thank you all for your support and well wishes. We wish you and your families many blessings."

Vivian Lake is the super couple's second child, joining big bro Benjamin, 3, and Brady's son from his relationship with Bridget Moynahan, John, who is 5.

In an unusual move, Bundchen, 32, never formally announced her pregnancy. Her burgeoning belly, however, told a different story. She told Vanity Fair in 2007 that she wants a large family. She married Brady, now 35, in 2009.
