He’s hunted down demons, gone after ghosts and come face to face with ferocious monsters, but Jensen Ackles is diving into a whole new dimension: daddy duty.

The Supernatural star, 34, and his wife Danneel are expecting their first child later this year, his rep confirms to PEOPLE exclusively.

The actress, who most recently played Jenn on Retired at 35, will debut her baby bump when she accompanies Ackles — who plays Dean alongside new dad Jared Padalecki on the hit series — to the People’s Choice Awards Wednesday, where the dad-to-be is scheduled to present.

The couple tied the knot in 2010 in the actor’s hometown of Dallas, Texas.
