Ed O'Neill has been a star in Hollywood for decades. Recognizable from such shows as Married With Children and Modern Family he can't go many places without attracting attention.
He's used to signing autographs and posing for pictures, but one picture in particular stands out, and O'Neill probably regrets it.
Even his daughter called him a "moron" after she saw it.
Ed O'Neill was at the LAX airport when a pretty young fan came up and asked for a picture. Nice guy that he is O'Neill obliged. It wasn't until he checked Twitter the next day that he realized his mistake.
He told Ellen all about it after the talk show host peppered him with questions about his embarrassing mistake.

O'Neill had been approached by Modern Family superfan Britney Spears.
"No, I had no idea it was her," the 71-year-old told Ellen. "Look at my face do I look like I'm sitting with Britney Spears?"
He said he just thought it was an ordinary fan, but when he looked at his Twitter following the next day his audience had exploded.
At least his embarrassment will keep the ultra-successful O'Neill humble.
