Matthew McConaughey and Camila Alves welcomed a son Monday night, the actor’s rep Alan Nierob confirmed. Their baby was born at 6:22 p.m. in Los Angeles, weighing in at 7 pounds, 4 ounces.

McConaughey, one of People’s Sexiest Men Alive, initially announced the pregnancy on his website. "Camila and I made a baby together … ," he wrote. "We are stoked and wowed."

No news on the little dude’s name yet. But word is he looks a lot like his hunky surfer/actor dad.

He arrived shirtless. Totally cool.
