Gossip Girl's Matthew Settle & Wife Expecting

Matthew Settle, the father of Penn Badley and Taylor Momson's Gossip Girl characters, is "thrilled" to be an expectant father in real life,

"I'm not ready. I don't think I'll ever be ready," he told PEOPLE on Tuesday night. "But I'm thrilled."

Matthew and his wife, actress Naama Nativ, are expecting a girl,

"We're having a girl. It's going amazingly. I love it. He's very happy, very excited."

Matthew goes on to describe his feelings about expecting his first child,

"Before you have a child, everything is about you. But my wife, and us having a child, makes me want to be a better man."

Matthew and Naama are still undecided on a name for their daughter,

"We're not sure yet ... we'll see," said Naama. "I want Angelica."

Congratulations to the Nativ-Settle family!
