When Katy Perry's Prismatic world tour kicked off May 7 in Northern Ireland, audience members were treated to a video montage of the "Roar" crooner sticking her finger in her mouth, spitting up blue and green paint, and splashing it everywhere in a stark white room and all over herself.
Perry's stunt comes just a couple of months after performance artist Millie Brown vomited on Lady Gaga (on purpose) during the singer's performance of "Swine" at the SXSW festival in Austin in March.
The on-stage gross-out drew criticism from the likes of Demi Lovato, who accused Gaga of glamorizing eating disorders.
"Sad… As if we didn't have enough people glamorizing eating disorders already. Bottom line, it's not 'cool' or 'artsy' at all," Lovato wrote after the pair's performance, adding, "Would you let someone bring a needle and shoot up on you? Addiction is addiction."
While it's not clear if Perry's paint-puking performance was some sort of wink to Gaga, it is a bit ironic considering the "G.U.Y." singer appeared to be throwing shade Perry's way earlier this week.
During a Twitter Q&A with Mother Monster, Gaga tweeted, "It looks like green hair and mechanical horses are the thing now [eyeballs]." It just so happened that Perry had just rocked a green wig and rode a mechanical horse during her first performance of her tour Wednesday.
The ARTPOP singer, who has also sported green hair and ridden mechanical horses in the past, recently addressed comments about comparisons between her and Perry, saying, "I don't know what the f--k I have to do with Katy Perry. My music is so completely different and I couldn't be more different."
And yet, their onstage performance tactics seem to be a bit of the same.
