The former Disney star had a series of blockbuster hits in the earliest years of her career including "The Parent Trap", "Freaky Friday" and "Mean Girls".
Her career came to a halt when she experienced a torrid timeline of multiple arrests, went to rehab on numerous occasions throughout the late 2000s and became entrenched in legal conflict over an array of misdemeanors and probation violations.
