For Kaitlin Olson and Rob McElhenney, looking back on their whirlwind romance will always be a sunny time. The couple first met when Olson auditioned for the role of Sweet Dee for McElhenney’s show, It’s Always Sunny in Philadelphia.

The It's Always Sunny in Philadelphia costars, who met on the FX show in 2005 and married in 2008, welcomed their first son, Axel, in 2010. Their second son, Leo, joined the family in 2012.

Those who have seen It’s Always Sunny In Philadelphia surely know it’s not exactly a family-friendly show. The Paddy’s Pub gang has been known to be overly destructive, extremely offensive, exploitative and irredeemably immoral people.
