Delta Goodrem kicked her shoes off and put her feet up in a recent episode of The Voice Australia, blissfully unaware of the meltdown her unwashed extremities would trigger on social media.
The 'Born to Try' singer displayed the grubby soles of her feet while judging the blind auditions, but the real judgement was handed down in the form of viewers' horrified reactions on Twitter.
"Can Delta Goodrem wash her feet before sticking them in a camera lens?" one Twitter user asked.
"Someone get Delta a foot spa," wrote another, while some simply used several 'vomit' emojis.
"Delta's feet are filthy!" another tweet read, while one fan suggested the Aussie songstress was "too rich" for her feet to look like that.
Australian radio host and Goodrem's friend Jackie 'O' Henderson weighed in on the conversation, saying "she's probably embarrassed about it".
"If you walk around barefoot, you're going to get dirt on your feet! She probably didn't even realise," Henderson said on her radio show on Tuesday morning.
