As for the newborn's name? Padalecki is still keeping tight-lipped about that detail. "We just wanted to wish everybody out there a safe and happy holiday season, from the four Padaleckis. Sincerely: Me, @realGpad, Thomas, and," he teased again on Christmas Day. "Those damn 140 characters ALWAYS get the best of me! Embarrassingly, it cut off our new sons name! Sheesh. Crazy!
