The popular entertainer appeared on the September 9th broadcast of JTBC's 'hoguchart'. Her recent nude photoshoot previously made headlines, leading to netizens asking whether it was photoshopped.

Netizens have been commenting their amazement, stating: 

"I bet the calories of her 6 meals is more than one of my meals..."

"She's amazing to get real results instead of relying on CG."

"Amazing."
