Christmas came a few days late for the McConaughey clan with the arrival of a baby boy, whose birth was announced by his proud dad on Facebook the following morning. "Camila Alves gave birth to our third child yesterday morning. Our son, Livingston Alves McConaughey, was born at 7:43 a.m on Dec. 28, 2012," McConaughey wrote. "He greeted the world at 9 lbs. and 21 inches. Bless up and thank you for your well wishes." Livingston joins older siblings Levi, 4, and Vida, 3, in the McConaughey family.
