This is how Mother Monster gets clean.
The 27-year-old pop star posted a photo of herself naked in murky colored water after artist Millie Brown disgorged colored milk all over her while she performed "Swine" on March 13 in Austin, Texas.
"I loved every moment with you Austin. Last nights show healed my soul. Creative Rebellion is ARTPOP. Release yourself from every expectation. Be free," Gaga wrote along with the photo on her social networking site, Little Monsters.
