It's Always Sunny In Philadelphia's Glenn Howerton and his wife Jill Latiano are parents! Son Miles Robert arrived on September 12th, Glenn revealed on a Wednesday appearance on Conan. Glenn said of naming his son, "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. Then we saw him and he looked like a tiny little baby alien grandpa creature and I was like, 'I'm not getting any information from this. At all.'"

Glenn and Jill announced their pregnancy in July.

Congrats!
