Actress and film producer Sadie Frost says the sexism she has encountered has come from other women.
Sadie, who has starred in films including Empire State (1987) and Love, Honour and Obey (2000), said she was often asked about her ex-husband Jude Law by female journalists.
"I've encountered a lot of sexism from other women," she told The Observer magazine. "It's female journalists who tend to talk about my ex-husband or my divorce settlement.
"When I was on Woman's Hour recently, the presenter really went for the jugular."
The 51-year-old, who also runs fashion label Frost French, said she was motivated by others' doubts.
She explained: "Being doubted makes you driven. If I got the accolades I wanted, maybe I wouldn't bother to get out of bed.
"Though it would be incredibly shallow if my main worry was what people think about me."
With four children between the ages of 25 and 14, Sadie said she had once tried to be a "supermum" but was now more relaxed.
"A few years ago I used to get up at 5am and make a smoothie and meditate, and then try and be supermum," she said.
"Now the health stuff fits into my life. I'm not fanatical about it. It's crazy to pooh-pooh it though."
She added: "I'm a tough person. I think as you get older you have to be realistic, so I don't indulge in crying."
