Matthew McConaughey: It's a Boy!

The actor and his girlfriend welcome a son, their first child together

Matthew McConaughey is a proud new pop. (Although someone should probably tell him that all new babies arrive sans shirt.)

The ab-fab actor and his girlfriend, Brazilian model Camila Alves, welcomed a 7-pound, 4-ounce boy, their first child together, Monday evening, E! News confirms.

The youngster was born at 6:22 p.m., according to McConaughey's rep.

But while this may cut into the Texan's time for sojourns to Nicaragua and lazy days on the beach with Lance, the Sahara star sounds more than ready to embrace daddyhood.

"A healthy baby boy was born," McConaughey said tonight in a statement to OK! magazine.

"Camila and I were side by side the entire time. We are both tired and elated, and are so happy to have created the greatest miracle in the world—having a child and making a family. Now comes the greatest adventure—raising one, together."

McConaughey first spread the good news of Alva's expectant status on his reggae-playing website.

"My girlfriend Camila and I made a baby together," McConaughey blogged in January.

"It's 3 months growin in her womb and all looks healthy and lively so far. We are stoked and wowed by this miracle of creation and this gift from God, and so excited for the adventure that will come in raising this child, being mother and a father, and shepherding him or her through this life."

McConaughey's mother added her own rapturous comments to the site a few days later: "Just when I think life cannot get any 'SWEETER,' Matthew and Camila fill life with more...so here I am DRINKING FROM MY SAUCER, BECAUSE MY CUP IS INDEED OVERFLOWING WITH THIS NEW BABY," she wrote.

The child's name has not yet been released.
