AceShowbiz - Kate Beckinsale believes her super high IQ has been a "handicap" in her Hollywood career.
The actress opened up about her skills during a chat on "The Howard Stern Show" and admitted her mum had her IQ tested "because very bright children are nearly unbearable."
When host Stern asked if she was in the "genius" ranks, which is classed as anything over 140, Kate replied, "I think it was quite high, yeah. I'll have to text her."
"(Although) they tested me when I was young, so I mean I'm sure I've burned a few brain cells by now."
After her mum didn't reply to her texts, Kate gave her a call and discovered that her exact IQ score was 152.
But the screen star admitted that being brainy has been of little help in forging a career for herself in Tinseltown.
"Every single doctor, every single person I've ever come across has said, 'You'd be so much happier if you were 30 per cent less smart,' " the "Jolt" star sighed.
"It's no good to me, though. It's really not helpful to me in my career. I just think it might have been a handicap actually."
Kate Beckinsale shares daughter Lily with ex Michael Sheen and the girl follows in mom and dad's footsteps in movie industry.
In a previous interview, Kate insisted she wouldn't impose any recommendations on daughter, "I think it's really important to her to have her own thing, to go her own way and do her own things."
She's also happy Lily switched to her father's last name to avoid comparison.
