8. Fergie – Was Addicted To Meth
Fergie may have made it big with the Black Eyed Peas, but before that she was performing with the group Wild Orchid. The main issue with this band? Fergie developed an addiction to crystal meth while she was with the group, and stayed addicted even after she had moved on from them. Fergie has been open about her usage in the past, claiming that meth was “the hardest boyfriend I ever had to break up with.” She also stated that “a lot of it was being a child actor; I learned to suppress feelings.” Fergie claims that she used hypnotherapy to help her in her recovery from crystal meth.
