Pop star Lady Gaga is known for her shocking outfits and antics. But what she did on stage Thursday night at the South By Southwest festival in Austin, Texas, has left even some of the most desensitized critics calling it “ridiculous” and “sick.”

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 then sticks 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 Lada 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.”

And there’s even more irony: Gaga revealed during an interview with ABC late night host Jimmy Kimmel that she was wearing a coffee filter dress to cover herself up because she felt fat. That as she was having someone stick their hands down their throat and vomit on her.

Did her performance go too far?
