The Blind Side star admits her mum Helga forbid her from joining friends at social gatherings and she was lucky to even go to her high school dance.
She says, "My mother was very strict but rightly so, I think. She just didn't want me in a car with any boys whatsoever until I was 18... I was allowed to go on a date twice - to a dance. But I had to call every 20 minutes. (I had to go) to the payphone. Helga would have shown up at the school, which she did as well, when she didn't hear from me."
But Bullock admits she's turned into the same overprotective parent since becoming a mum to adopted two-year-old son Louis - and she's beginning to follow in her mother's footsteps.
She admits, "I don't hover, but... he's always in a helmet and in this bubble that I keep him in."
