Supermodel Gisele Bundchen and New England Patriots quarterback Tom Brady welcomed their second child Wednesday -- a baby girl they've named Vivian Lake.

X17online's exclusive photos of Bundchen sporting a baby bump while vacationing in Costa Rica back in late July confirmed rumors the Brazilian beauty was pregnant.

It's the second child for Gisele - they have son Benjamin, 2, and Tom's third child - he has a son John, 5, from a previous relationship with actress Bridget Moynahan.

Gisele announced the happy news to her fans on her Facebook page, along with this photo:

    "We feel so lucky 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."
