Brazilian supermodel Gisele Bundchen has given birth to her first child -- a boy -- with U.S. football star husband Tom Brady.

Brady told reporters the baby, who is yet to be named, was born on Tuesday, calling it the most wonderful experience in my life.

Speaking to sports reporters, the quarterback for National Football League's New England Patriots said Bundchen and the baby were in good health.

The bay is a first for Bundchen, 29, and a second for Brady, who has a two-year-old son with actress Bridget Moynahan.

Bundchen, who previously dated Titanic actor Leonardo DiCaprio, married Brady in February.
