Schumer, 34, was recently photographed chowing down on a sandwich while out in New York City Thursday. The Daily Mail said it contained ham, adding a joke referencing the name of her Comedy Central show: "It didn't take that sandwich long to end up Inside Amy Schumer."
"No! It was prosciutto from @defontesBrklyn I'm no sucka," the comedienne and actress tweeted. "Also that was a great joke! Love chava bracha."
Clarkson, 33, replied to Schumer about an hour later with her own food-shaming pic, showing her eating a hot dog at the beach in 2006. The image is the first one that shows up when you Google "Kelly Clarkson hot dog."
