8. Charlie Sheen
Staying true to his reputation, Sheen was expelled just weeks before graduation for his terrible grades and attendance. Why are we not surprised.
Sheen attended Santa Monica High School in Santa Monica, California, where he was a star pitcher and shortstop for the baseball team.
Not only this, but he was very involved in film-making at that time too, making Super-8 films with his school buddies and acting in them. And who were his buddies you might ask? None other than Rob Lowe and Sean Penn!
