It's a boy!
No, seriously, it's really a boy for Matthew McConaughey and his love Camila Alves. Despite earlier reports that the couple had welcomed a baby girl, McConaughey took to his Twitter account to announce that their third child was a son.
"Our son, Livingston Alves McConaughey was born at 7:43am on 12.28.12," the actor tweeted. "He greeted the world at 9lbs. and 21 inches."
Livingston joins big brother Levi, 4, and big sister Vida, 2.
