Met Gala 2015: Kim Kardashian and Kayne WestReuters

Kim Kardashian may have long forgotten her former boyfriend Ray J and the infamous sex tape she made with him. However, some people are not ready to let it rest, as proved by one man who took a screenshot of an explicit image from the movie and exhibited it at her husband Kanye West's concert.

West, who was performing at the Glastonbury Music Festival in Somerset, England, encountered an indecent heckler, who went to the trouble of printing the photo of Kim Kardashian with her then-boyfriend Ray J just so he could wave it at Kanye as he performed for the crowd.

Kim was reportedly at the event, and the concertgoer's aim was to "sl*t shame" the "Keeping Up With the Kardashians" star. Neither Kim nor Kanye has commented on the issue, so it is not known if the lewd flag was visible from the stage.

Luke Hopson has shared the image of the flag on his Twitter page, saying they should look out for the flag at the '#Glastonbury2015" festival. Although some people have joined Hopson in shaming the celebrity, many others went on to shame his actions:

Laurie Fothergill ‏(@laubbie_) :"i hope someone has your regrets on a flag when you're Achieving something great..."

Harry ‏(@harridando): "@KimKardashian @kanyewest @RayJ more successful than you, and doesn't care at all what you have to think or say..."

The sex tape was supposedly made in 2003, when Kim was in her early 20s, before her perfectly round rear and pouty lips became tea-time topics. The tape is said to have played a huge role in bringing global stardom to Kim, who was merely known as the friend of socialite Paris Hilton at that time.
