Rachel Bilson has revealed that her mother, Janice- who is a sex therapist and a relationship counsellor - knew when she lost her virginity.
The 31-year-old actress told Cosmopolitan magazine that she is comfortable discussing her personal life with her mum, Contactmusic reported.
She said that her mother could intuitively tell when her daughter had lost her virginity and so she didn't even question her.
Bilson asserted that her mum explained her all sorts of things about relationships including how important it is to be honest and have trust.
