Dustin Diamond
Dustin Diamond starred in Saved by the Bell back in the 1990s. After the show ended, Diamond struggled to get his life together. In 2014 he was arrested for stabbing another man over a petty dispute. He racked up some immense debt in prison, and when he got out he attempted to sell signed t-shirts to make his money back. He even tried to sell a sex tape (which was proven to have been faked) and wrote a series of memoirs that documented the alleged drug use and sexual nature of the backstage of Saved by the Bell. His adjacent co-stars have all come out to denounce the claims Diamond made in his books.
