Lady Gaga has spoken out about her recent SXSW performance where she was vomited on by vomiting performance artist Millie Brown.

The singer spoke about her performance of “Swine” during a TV interview and described it as “art in its purest form”.

Singer Demi Lovato has previously criticised the performance as “glamorising eating disorders” but Gaga disagreed, defending her decision.

"I guess we weren't completely surprised. [Millie Brown] and I know that not everybody's going to love that performance.

"But we both really believe in artistic expression and strong identities. I support her and what she does. ARTPOP, my new album, is about bringing art and music together and the spirit of creative rebellion.

"For us, that performance was art in its purest form. But we totally understand that some people won't be into it."

She did emphasise that it wasn’t her intention to cause controversy from the performance.

"Did we want the controversy? I suppose it doesn't matter.

"Either way, we don't make things for any intention in particular other than in the spirit of entertaining the crowd and creating something that is really for the moment.

"It wasn't meant for the Today show. It was meant for a club performance in Austin, and we had a great time."
