The pop star - who has 70.9 million followers on Instagram - continued: "This is absolutely harmful to anyone who is easily influenced by societal pressures put on us from the diet culture to constantly be losing weight in a world that teaches us to equate our value and worth with the way we look and especially anyone in recovery from an eating disorder.
"Especially when eating disorders are all about 'control'. So please Instagram, keep this off mine and other's feeds who could be easily effected by this disgusting advertisement.
"With how aware people are becoming of mental health and mental illnesses, I expect you guys to know better by allowing this advertisement to be allowed on your app. And shame on the game. (sic)"
In response to her post, Instagram has issued an apology via TMZ.
The company said: "We're sorry. This ad was approved by mistake. We reviewed it again and removed it from future delivery in people's feeds."
