Rachel Weisz's son thinks she looks "awful" when she goes to red carpet events.
The 45-year-old actress insists nine-year-old Henry - who she has with ex-fiance Darren Aronofsky - isn't "very interested" in her career and has never even seen one of her movies.
She said: "He's really not very interested in that side of my life.
"I suppose he must be aware of it but as far as he's concerned, I'm just Mum.
"He's never seen a film of mine.
"If he sees me in make-up and a dress ready to go out to an event, he thinks I look awful. He doesn't like make-up. He's got good taste."
And the 'Youth' star - who is married to James Bond actor Daniel Craig - is in awe of her son's imagination.
She said: "He's got a wide and boundless imagination.
"He's constantly building and drawing and creating stories. At the moment, it all features lots of battles between good guys and bad guys and I don't have to do anything to encourage it at all. It's just what he does."
