"A friend of mine says it's a slightly different gear, and I said, 'Different gear? No, you put it in park, you get out of the car, you get in a different car, you take a left down a wrong street,'" he adds. "That's basically where I'm at now."

Getting back into the groove at work has been an adjustment for Ackles, who recently began production on Season 9 of his CW series. "I'm just completely lost," he says. Nevertheless, he says that "the baby's doing great."

Ackles isn't the only "Supernatural" star with a baby on the brain: his co-star, Jared Padalecki, is expecting his second child with his wife, Genevieve Cortese. Us Weekly exclusively shared the actors' happy news on July 21. Padalecki, 31, later tweeted a picture of his son, Thomas Colton, 16 months, holding his mother's sonogram.
