Mischa Barton credits her sister with her acting success - she discovered the stage after her sibling abandoned her at a summer camp. The former star of The O.C. was just eight when a talent scout spotted her potentials.

She explains, "That's how it happened. I remember going to camp with my older sister, who completely ditched me because she was 16 and I was eight and I was uncool to have around. I ended up doing all these monologues and it paid off, because some agent came up to my mom and said I should try acting."
