Matthew McConaughey, Camila Alves welcome third baby

It’s baby No. 3 for Matthew McConaughey and Camila Alves, according to reports out Friday.

The tot — supposedly a girl, though that’s unconfirmed — was born in the morning in a hospital in Austin, Texas, TMZ said. She (if she is a she!) joins 4-year-old brother Levi and 2-year-old big sis Vida.

[Updated, 9:20 a.m. Dec. 31: Strike that! It’s a baby boy, McConaughey confirmed Saturday via Twitter. “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.”]

The actor, 43, and Alves, 29, were wed in June in Austin. “We decided to embrace the ritual of marriage as an opportunity and adventure we’ll take together,” the actor told People at the time. In front of a local pastor and a monk, the couple exchanged hushed vows, whispering them to one another with nary a bridesmaid or groomsman in sight.

The curious should keep an eye on McConaughey’s Twitter account, where on July 4 the couple announced that the baby was on the way. “Happy birthday America, more good news, Matthew and I are expecting our 3rd child, God bless, just keep livin,” they said.

See the new dad on-screen next in “The Dallas Buyers Club,” for which he got super skinny — like, at least 30 pounds down — to portray the real-life Ron Woodruff, who, after being diagnosed with the AIDS in 1986 and striking out with the one drug then FDA-approved to treat it, wound up smuggling alternative drugs into the U.S. for himself and eventually for others.
