Mischa Barton
Mischa Barton's claim to fame was her leading role as Marissa Cooper in The O.C., but that time in the spotlight sent her down a wild road. She was a known party girl, but in 2017 things went too far. Paparazzi got their hands on an x-rated tape she was allegedly in and demanded half a million dollars unless she wanted it leaked. Thankfully, the issue was settled, but things got pretty scary for a minute.
