It’s Always Sunny in Philadelphia stars Kaitlin Olson and Rob McElhenney welcomed a son Wednesday afternoon at their Sherman Oaks, Calif. home. Axel Lee McElhenney is the first child for the couple. “I went into labor at the Phillies/Dodgers game on Tuesday night,” Olson said in a statement. “As soon as Ryan Howard hit a three-run home run, we felt comfortable leaving to go have our baby…. We love him like crazy, even though he made us miss the second half of the game.” The couple wed in Malibu in 2008.
