Matthew McConaughey and Camila Alves have a new baby daughter, reports US Weekly. It's their third child—along with Levi, 4, and Vida, 3—and the first since they wed earlier this year. TMZ's insider says the 43-year-old McConaughey was present for the birth at an Austin hospital and looked like he was finally putting weight back on. He had gotten downright emaciated to play an HIV patient in the upcoming Dallas Buyer's Club. He and Alves, 30, have been together since 2006.
