After a weekend relaxing on the beach [1], Matthew McConaughey's girlfriend Camila Alves gave birth to their baby son [2] in LA on Monday afternoon. His rep confirmed the great news and that the little guy weighed 7 lb., 4 oz., though we've yet to learn of a name for mini Matty. We can't wait to hear more about another new celebrity baby who shares a bday with Sunday Rose Kidman Urban [3]! Congrats to the growing family and new parents!
