Jared Padalecki's life changed forever on Monday.

The Supernatural actor and his wife Genevieve Cortese welcomed their first together, Padalecki announced via Twitter. "It's a boy!"

In January, Padalecki -- who's also appeared in New York Minute with Mary-Kate and Ashley Olsen and House of Wax with Paris Hilton and Chad Michael Murray -- told Us Weekly his wife planned to have a natural childbirth with a midwife. "I'm taking the epidural shots!" the actor joked.

Padalecki, 29, also said they would be taking their time before naming their firstborn. "We don't want to put it out there, like try and turn him into something before we meet the kid," he told Us. "We want to get a feel for who this kid is before we name him."

The actor and Cortese married on February 27, 2010 in Sun Valley, Idaho.
