Sam Winchester's going to be a daddy!

Supernatural's Jared Padalecki is set to be a first-time dad, he confirmed on Twitter Tuesday.

"OK yall I'd rather you officially hear it from me.. So, yes. Genevieve is pregnant. We'll be welcoming a new member to our family in 2012 :)" the actor wrote, referring to his wife -- and former Supernatural costar! -- Genevieve Cortese.

The couple married on February 27, 2010 in Sun Valley, Idaho.
