Actress, singer, partier, she's barely into her twenties, and Lindsay Lohan has already gone from screen tests to rehab stints. She was acting in a soap opera by the age of ten and made her film debut in The Parent Trap a year later. Unlike many child actors, Lindsay's appeal seemed to grow as she as she aged, and by 2005 she was headlining hit films such as Mean Girls. Despite her popularity as an actress, press accounts focused more frequently on her antics as a Hollywood party girl. In addition to her alleged problems with substance abuse, her clashes with co-stars and studio execs, and her widely reported trips to rehab, Lindsay has added "singing sensation" to her film career, having released her debut album in 2004.
