Ed ONeill Once Mistook Britney Spears For A Big Modern Family Fan

Ed O'Neill sat down with his "Finding Dory " co-star Ellen DeGeneres on Monday to discuss the sequel to the beloved Pixar film "Finding Nemo." The "Modern Family " star, however, may have been the only person in America who wasn't overjoyed about the news of the long-awaited sequel.

"I got a call from my manager and he said, 'Do you want to do something on "Finding Dory"?' and I said, 'What is that?'" O'Neill told Ellen, adding that he agreed to play the part of a disgruntled octo- septopus without ever seeing a script. 

"When I showed up, I thought it was a cameo. I kept saying, 'It's one day, right, guys? I'm doing one day,'" he said. "So I did the one day, and they called me back, and you know, after, like, months and months, almost a year, I thought, 'This is kind of a big part.'"

O'Neill had another hilariously clueless moment recently when he was approached by someone he believed was simply a "Modern Family" fan in LAX on his way to Hawaii. 

“She came up and said, ‘Oh, Mr. O’Neill, I love "Modern Family" and you’re my favorite on the show.’ And I said, ‘Well, I’m here. I’m the only one here,’” he joked, adding that the fan "couldn't have been nicer." 

The actor received a text from his manager the next day, alerting him that he had unknowingly taken a picture with Britney Spears and it had received thousands of likes after she posted it to her social media.

 “No, I didn’t know it was her! Look at the look on my face. Do I look like I’m sitting with Britney Spears?” O’Neill said.
