Ariana Grande has been at the centre of global conversation this week after displaying her alarmingly thin frame in the music video for Petal.

The singer, 33, previously requested that fans do not comment on her body – with the Petal video ironically being a social commentary on the pressure to conform to Hollywood's exacting beauty standards.

However, many fans and prominent figures have felt compelled to speak out to express their genuine concern for Ariana's health and wellbeing, with many citing Karen Carpenter as the reason.

It's been 43 years since Karen tragically succumbed to anorexia, dying from cardiac arrest at the age of 32 after the world slowly watched her deteriorate.

Ignorance about eating disorders, pressure to maintain a wholesome family-friendly image, and denial by those around her have been blamed for Karen's untimely death.
