He writes on his WhoSay page:
Camila (@iamcamilaalves) gave birth to our third child yesterday morning. Our son, Livingston Alves McConaughey was born at 7:43am on 12.28.12. He greeted the world at 9lbs. and 21 inches. Bless up and thank you for your well wishes. Happy New year, and just keep livin, Camila and Matthew McConaughey.
Might the name have something to do with McConaughey's favorite phrase, "Just keep livin"?
He first uttered it as Wooderson in 1993's Dazed and Confused, and the phrase went on to inspire McConaughey's j.k. livin foundation and the j.k. livin store.
Next up for McConaughey? Playing an HIV/AIDS patient in The Dallas Buyer's Club.
