“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 balls to my very, very male world. We found out I was pregnant during my mom’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.” – It’s Always Sunny in Philadelphia‘s Kaitlin Olson to People, on being pregnant with her second baby, another boy, with husband Rob McElhenney.
