Now it appears as though Perry is doing more Gaga-esque stunts. Perry appears to have copied the routine from South by Southwest in which British performing artist Millie Brown vomited green and black paint on Gaga. On a pre-taped video displayed on a screen, Perry puts a finger to her lips and then allows the paint-like substance to fall out of her mouth. Gaga was previously criticized after the March 13 performance for what many said "glorified" bulimia.
Perry's tour continues tomorrow at the LG Arena in Birmingham, England. After the European tour ends, she will arrive in North America on June 22 at the PNC Arena in Raleigh, North Carolina.
