And baby makes five!

Matthew McConaughey** and wife Camila Alves** have something extra to be thankful for as they head into the new year: Their new baby daughter, who was born the morning of Dec. 28 in Austin, Tex., a source tells Us Weekly. (TMZ was the first to break the news.)

The couple's new arrival joins older siblings Levi, 4, and Vida, 3.

Confirming Alves' third pregnancy via Twitter on July 4, McConaughey's announcement came two weeks after the couple tied the knot in an outdoor Austin, Texas ceremony. "Happy birthday America, more good news," the Magic Mike actor tweeted last summer. "Camila and I are expecting our 3rd child, God bless, just keep liven."

As they had done with their older children, McConaughey, 43, and his wife decided not to find out the gender of baby No. 3 ahead of time. "It's a wonderful surprise," the proud new papa has said.

While her pregnancy progressed, the Brazilian model mom-to-be, 30, proved that she wasn't afraid to stay sexy while expecting, and dressed her bump in a variety of form-fitting fashions. "Do not be afraid to be sexy while you're pregnant, she told Us when offering advice to other fashionable pregnant women. "I'm learning that on my third pregnancy. I'm like, 'oh wow, you don't have to wear just flowing things.'"

Together since 2006 after meeting in a Los Angeles bar, the actor and the Brazilian-born model got engaged on Christmas Day in 2011, and said their "I do's" on June 10. Setting up a makeshift campground on their Austin, Texas property, the pair invited their children to take part in the ceremony: Levi was the ring bearer and Vida the flower girl.
