11. Haley Joel Osment
You probably remember Haley Joel Osment as a cute 10-year-old in the 1999 film, The Sixth Sense. But now he’s 27, and while he’s still acting (he has a role in the Entourage movie), he definitely hasn’t lived up to what was expected of him after he was nominated for an Oscar for his Sixth Sense role.
At least part of the reason has got to be that he didn’t exactly age into a handsome adult. Some child stars just aren’t meant to have a long career in show business.
