The Glasto fan brought the flag with them to Kanye's headlining set on the Pyramid Stage on Saturday evening, where he was cheered on by wife Kim.
We wonder if she saw the flag?
Reality star Kim was propelled to international fame in 2007 when a sex tape she'd recorded with Ray J four years previously was leaked online.
Kim, who married Kanye last year, has since admitted on several occasions she regrets making the tape: "I felt humiliated -- why would anyone put that humiliation on their family like that?I'm definitely not grateful for that experience. I would say if I had one regret, that would be it. If I were to do it again, obviously I wouldn't do it again."
