'It's Always Sunny' Stars Kaitlin Olson & Rob McElhenney Are Expecting! Congrats!

Sweet Dee’s pregnant… again! The couple are having their second child this spring

It’s Always Sunny in Philadelphia stars Kaitlin Olson and Rob McElhenney already have a 13-month-old son named Axel Lee. Now they’re having another son, according to People!

“We’re having a boy! We’re so happy that Axel gets to have a brother so close in age. And that I get to add another set of ball to my very, very male world,” the actress — who plays the character Sweet Dee on Sunny —  joked to the magazine.

She said they found out she was pregnant during her mother’s birthday weekend in Ojai. “I was instantly so proud of this baby for already knowing how to make someone else’s special day all about him,” she laughed.

Kaitlin and Rob married in 2008 and both are characters on the FX comedy. But they aren’t the only couple on set expecting — co-stars Charlie Day and Mary Elizabeth Ellis are expecting their first child in December! And, according to People, cast mates Glenn Howerton and David Hornsby both welcomed sons last month.

We’re so happy for the couple and that the Always Sunny family is growing! With all the new babies around set, it must be a fun time there!
