It's Always Sunny Stars Reveal Early Secret Romance Impact

Rob McElhenney and Kaitlin Olson, stars of the long-running sitcom It's Always Sunny in Philadelphia, began dating secretly during the show's early years, a revelation that initially shocked and concerned their co-star and McElhenney's then-roommate Glenn Howerton. Howerton feared their relationship could jeopardize the show, expressing that if their romance ended badly, it could ruin the series and the jobs of everyone involved. Despite these concerns, McElhenney and Olson married in 2008 and have two sons, with their relationship becoming a celebrated part of the show's history. The rest of the cast, except for Danny DeVito, was unaware of the romance for months; DeVito sensed the budding relationship early on, noting the couple's natural gravitation toward each other. Olson nearly missed landing her role as Dee due to a minor audition flub, but ultimately her comedic instincts and insistence on reshaping the character proved pivotal. The couple's romance, which began amidst the chaos of producing a groundbreaking sitcom, has endured and become a beloved story behind the scenes of the series.
