Eww! A woman walked onstage and vomited all over Lady Gaga during her performance of “Swine,” at SXSW! Watch the crazy video!

Crazy Video! Woman Vomits on Lady Gaga at SXSW Show

Of course, the woman was a pro puker, hired to guzzle a green liquid and then forcibly throw up on the singer.

The bizarre show also included roasting Mother Monster on a BBQ spit, a woman provocatively eating sausages, and Gaga riding a mechanical pig while playing the keyboard. Before the show, the 27-year-old singer, who was sporting dreadlocks for the performance, tweeted this sneak peek pic with a "little friend."

The #BoldStage concert was a celebration of Lady Gaga’s Born This Way Foundation and attendees could only gain entry by performing a Doritos Bold Mission. 

Some of the missions included jumping from a 30-foot high platform to grab a ticket to the show, competing in a roller derby while wearing a sumo wrestler suit, and more.

We are pretty sure getting barfed on wasn’t on the list.
