Announcing the news during an appearance on late night talk show Conan on Thursday (15Sep11), Glenn Howerton admitted the couple had waited until after the tot's birth to find a suitable name.

He said, "My wife and I thought it would be a good idea to wait to see the baby first before we actually decided what his name would be… get a sense of the guy.
