Meet Matthew McConaughey's new daughter Vida!

On his official website, the actor, 40, and girlfriend Camila Alves have released the first photo of their baby girl, who was born Jan. 3 in Los Angeles (she weighed in at 7 lbs., 7 oz.).

"Our latest family member, Vida Alves McConaughey," McConaughey wrote under the baby's photo.

Alves, who makes her debut as host of the Bravo hairstyling reality show Shear Genius on Feb. 3, tells the new Us Weekly (out now) that the baby "is doing great."

"It's easier with the second child, because, you know what she'll be like," said Alves, 27, who welcomed their first child, son Levi, in 2008.

She said their 19-month-old son is "at the fun stage where he's talking. He loves saying Vida's name!"

McConaughey couldn't be a more doting dad, she added.

Said Alves, "To see a father with his child is beautiful."
