Matthew McConaughey and Camila Alves expecting baby no. 3

Just two weeks after marrying, Matthew McConaughey and wife Camila Alves announced they're expecting a third child.

"Happy birthday America, more good news," the actor tweeted on Wednesday (July 4). "Camila and I are expecting our 3rd child, God bless, just keep liven."

The new baby will join big brother Levi, 3, and sister Vida, 2.

The "Magic Mike" star and Alves have been together since meeting in a Los Angeles bar in 2006. An engagement came on Christmas Day 2011 and the couple married on June 10 at their Austin, Texas property.

"Levi brought the rings on a necklace. Vida was the flower girl," McConaughey told NBC's "Today" show. "I don't think she dropped one petal."
