The 38-year-old actor, Penn Badgley
's father on the CW hit, will be a real dad in March: He and his wife, actress Naama Nativ, are expecting their first child.
It's the best thing that's happened to me. We've been getting ultrasounds: It's starting to wave. I sing Sinatra to the baby and Naama can feel it move.
HOW DID THE CAST REACT?
The kids were thrilled because they are going to be aunts and uncles. I won't have a shortage of babysitters.
WHAT IS IT LIKE BEING A SEXY TV DAD?
It's embarrassing at times. There are girls that come up and say, "You're hot" in front of my wife. She's like: Thank you, I think!
