The 27-year-old singer played on the Doritos #BoldStage in Austin, Texas. When Gaga performed her song "Swine," a woman shoved a finger down her throat and vomited all over the pop star. The musician continued to bang away at the drums as the woman spewed a green, slime-like substance.
Gaga performed for 2,000+ Little Monsters during her first-ever SXSW performance. Fans were granted admission only after they proved themselves by completing a Doritos Bold Mission. The event aired on Fuse and will be rebroadcast on March 29. It celebrated Gaga's Born This Way Foundation.
