Scarlett Johansson works out four days a week to stay around a size two. She becomes a major star on the big screen thanks to her athletic figure and energetic roles, such as playing spy Black Widow in the Marvel Cinematic Universe and cyber-human Mira in Ghost in the Shell.

But Scarlett insists her commitment to exercise is as much to do with her mental health, as it is her physical health. In an interview with Stylist, she said: 'For me, wellness is a huge part of my mental wellbeing. 

'I try and do some sort of exercise around four days a week if I can. I've been doing Pilates for the last eight years or so, and I've found it to be amazing.'

'When I saw that photo it just, you know, it brought everything back. All those painful memories.' In images from the late 1990s, the wife of SNL star Colin Jost can be seen with pimples on her forehead.
