Rachel Bilson failed to shine in auditions as she struggled to cope with the pressure attached to her famous surname.

The O.C. star's father, director/Tv script writer Danny Bilson, and her grandfather, Bewitched director Bruce Bilson, are both well known within the industry, and the actress insists their fame made the audition process harder for her.

She tells Britain's Cosmopolitan magazine, "My father is in the same industry so I'd grow up on set. But when I went for auditions, they'd be like 'I know your dad' or, 'I know your grandpa'. I'd feel so pressured that I would totally choke. It's like they would suck something out of me and I would just crumble under pressure and do terribly."
