The 42-year-old says that her skin wasn't always perfect, but her dermatologist told her to try eating the oily fish a day to help clear her complexion, reports femalefirst.co.uk.

"I used to have really problematic skin and he (dermatologist) said to me, 'You have to eat salmon every single day'. I said, 'Really, every day?' And he said, 'Yes; breakfast, lunch or dinner, you have to eat it every single day'," Beckham told The Edit magazine.

While the former Spice Girl boasts having perfect skin, she also shared that she has made a lot of fashion mistakes.

"I have made so many fashion mistakes but I actually don't look at them as mistakes. I celebrate those things. I laugh occasionally but I'm not ashamed of any of that," Beckham said.
