The Celebrity: Webbie
The Seizure: Before a show in South Carolina back in February 2008, the Louisiana rapper reportedly suffered a seizure that forced him to cancel.
What Went Wrong? We can't be 100% sure what happened or even that Webbie definitely had a seizure. He's steadfastly refused to talk about it and even denied that it ever happened, saying that he had too much to drink that night and that people thought he had a seizure when he didn't. He even infamously spazzed out on a radio host who asked him about it. But clearly something happened that night.
