Missy Elliott’s video for “WTF (Where They From)” features Pharrell, impressive choreography and dancing marionettes, but what you don’t see is the literal blood that went into making the clip. In the video, Elliott wears an outfit that has a bunch of small glass shards, which looks great since it essentially turned her into a human mirror-ball. However, the glass was sharp and actually cut into her skin a lot.

“We all came up with the glass outfit, which was the hardest thing to wear because it was really cut up glass so I was bleeding and everything,” she said. “I was so agitated but I had to get it done. I was bloody and bloodied. There was blood everywhere!”
