Demi Lovato has hit out at Lady Gaga for "glamorizing" eating disorders.
The "Heart Attack" hitmaker, who has battled bulimia in the past, took to Twitter to vent her frustration after the 27-year-old singer performed "Swine" at the South by Southwest festival in Texas, which involved vomitting artist Millie Brown.
Demi tweeted: "Sad... As if we didn’t have enough people glamorizing eat disorders already. Bottom line, it’s not ’cool’ or ’artsy’ at all.
"Would you let someone bring a needle and shoot up on you? Addiction is addiction."
However, the 21-year-old singer was forced to defend herself after her honest comments didn’t go down well with her fans.
She retaliated: "It’s not ’shade’ and it’s not ’hate’. But someone has to come forward and say it and I’ll take the heat for it."
Demi then reached out to Lady Gaga directly, writing: "@ladygaga you’re SO talented, if not one of the most talented in our industry PERIOD. Dope is INCREDIBLE.. but you don’t have to do that."
Meanwhile, Lady Gaga—who has also struggled with body image in the past—said yesterday she fears she had got "really fat" during her stay in Austin, Texas.
Millie, who has worked with Lady Gaga before, performs her stunt by drinking colored milk before sticking her fingers down her throat and vomiting the liquid back up.
Meanwhile, Millie has hit back at Demi’s bulimia claims.
The artist says there is a "clear difference" between her performance art and the eating disorder, and insists she didn’t intend to offend anyone when she made herself regurgitate during the singer’s performance of "Swine" at the SXSW Music, Film + Interactive Festival festival in Texas.
She told TMZ.com: "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."
