Millie Brown, one of Lady Gaga’s artistic collaborators has responded to criticism from Demi Lovato after the performer vomited brightly coloured paint over Gaga during a performance.

The stunt happened during Gaga’s performance of “Swine” during SXSW and sparked controversy from many people including Lovato who saw it as glamorising eating disorders.

Lovato herself has previously been open about her own struggles with bulimia and received treatment for the illness back in 2010.

After seeing the performance, Lovato took to Twitter to criticise, saying: "Sad... As if we didn't have enough people glamorizing eat disorders already. Bottom line, it's not 'cool' or 'artsy' at all."

Brown has responded in a statement which she posted to entertainment news website TMZ saying: "There's a clear difference between using my body to create something beautiful, to express myself and feel powerful, rather than using it to punish myself and conform to society's standards."

Gaga has yet to respond to Lovato’s complaints herself.
