While performing her song “Swine,” the singer was joined by someone named Millie Brown. Brown is an artist of sorts who specializes in painting with…vomit. That’s right, she ingests colored liquid and thensticks her fingers down her throat and literally vomits all over a canvas. On Thursday, Brown did just that — except there was no canvas: She vomited a green liquid onto Lady Gaga.

Even TMZ, the celebrity gossip site, thought it was too much. “Lady Gaga’s antics are sometimes inducing, but this is ridiculous,” the staff wrote, going on to call it “sick…literally.” source – The Blaze
