What would it be like having a sex therapist as your mum? Ask OC star Rachel Bilson, who tells Your Look magazine her mother knew everything about her sex life and gave her great relationship advice.

"She knew the day after I lost my virginity," Bilson says. "She starting talking to me about sex. She said, 'It happened last night, didn't it?'."

Bilson says her mum's approach has been "weird, but helpful"
