"Agent Carter" star Chad Michael Murray welcomes baby boy

Chad Michael Murray and his wife, actress Sarah Roemer, welcomed their first baby this weekend -- and it's a boy!

The "Agent Carter" star, 33, shared the news via Twitter on Sunday, calling his little one "God's greatest gift" while apologizing for missing former Buffalo Bills quarterback Jim Kelly's charity event.

The former "One Tree Hill" star continued to tweet about the joy of being a new dad -- but remained mum about what he and Roemer, 30, named the new tyke.

Murray has mostly kept his private life below the radar this year, confirming in January that he and Roemer had married and were expecting a baby only after he was spotted wearing a wedding ring at the Television Critics Association press tour.
