“It was me who had the affair,” Olson tweeted Monday, linking to an article on a celebrity gossip blog.
“But it wasn’t with someone from Wales. It was with a whale. I’ve always loved whales. They are the bosses of the ocean and I am drawn to the Force. We ask for privacy as we navigate this difficult time.”
The blog article suggested the couple were separated because McElhenney cheated on Olson in Wales, where he is co-owner of a football team with actor Ryan Reynolds.
McElhenney also got involved.
“Sad to admit the rumor is true,” he tweeted, sharing his wife’s post. “However, some details are…. incorrect.”
The couple married in 2008, three years after the premiere of their hit comedy series It’s Always Sunny In Philadelphia. They have two sons, Alex Lee, 12, and Leo Gray, 11.
McElhenney created and stars in the show along with his wife Charlie Day, Glenn Howerton and Danny DeVito. The 16th season is currently running.
