Lindsay Lohan
The Parent Trap actress became a megastar but descended into chaos. Everybody knows that Lohan suffered severe problems with substance abuse. She admits that she used cocaine a lot and drank heavily while spending a lot of time in rehab. It’s a shame because she possesses a lot of talent (via Huff Post).

But this story has a happy ending because Lohan cleaned up her act. After she disappeared out of nowhere she agreed to come back and work with Netflix. This means that she’ll appear on our TV screens again after years in the wilderness. It’s great that Lohan is no longer suffering from severe mental health problems.
