Art or not? Vomit artist Millie Brown throws up on canvas to create abstract paintings

Controversial vomit artist Millie Brown uses her own vomit to create abstract paintings. The artist uses a selection of dyed soy milk in a mixture of colours which she then swallows at various intervals, one at a time, before vomiting it onto a white canvas. Millie can be seen vomiting shimmering turquoise liquid over the singer in Lady Gaga's pop music video, Exorcist Interlude.
