Glenn Howerton of "It's Always Funny in Philadelphia" and his wife Jill Latiano welcomed their son Miles Robert on Monday, September 12, the actor revealed on "Conan" on Wednesday.

"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," Howerton told Conan O'Brien. "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.'"

The 35-year-old actor wed Latiano in 2009 and announced the pregnancy in July.

In August, the FX comedy "It's Always Sunny" was renewed for an eighth and ninth season, making it the longest-running comedy series in basic cable history.

The network president John Landgraf announced the pickups at the Television Critics Association summer press tour and said that "It's Always Sunny in Philadelphia" had also been optioned for what would be its 10th season.

The show was created by stars Howerton, Rob McElhenney and Charlie Day and Landgraf called it the "cornerstone" of FX's comedy brand.

"They literally had no experience writing, no experience directing," Landgraf said of the "Sunny" creators. "They literally made a pilot for $200 they shot in their back yard. They were so young and so willing to learn and we didn't bring in show runners over them. It was a good partnership. It started out so bare bones - Rob McElhenney was a waiter and didn't quit his job until season two."

The "It's Always Sunny in Philadelphia" season premiere aired on September 15 on FX.

Howerton is an executive producer and writer on "It's Always Sunny" and has also appeared in films like "Everything Must Go," "Must Love Dogs," "Serenity," "Two Weeks" and "Crank."
