The vomiter is no amateur, she's
actually a "Vomit Painter" (actual profession) named Millie Brown, who
is known for drinking various liquids and then vomiting them up unto a
canvas. In this case, the canvas was Lady Gaga.Gaga was playing drums on a song called "Swine" when Brown, after drinking neon green liquid, proceeded to stand over her, stick her finger down her throat and vomit the green liquid all over Gaga.
