Hold onto your wigs! Katy Perry kicked off her Prismatic World Tour in England last night, and while the costumes, wigs and props are extraordinary—see for yourself—not everyone is impressed. 

Lady Gaga—pop music's biggest lover of costumes and wigs—seems miffed by Perry's latest props. Earlier today, Mother Monster sent out the following ambiguous tweet, which Little Monsters and Katycats are seeing as a dig at Perry:

Gaga has been rocking shades of green hair since 2011, and she rode mechanical horses on her Born This Way Ball Tour as well as last year's American Music Awards. And while celebrity homages are an aspect of Gaga's performances, everyone knows the ARTPOP singer loves chatting about her influences whether it's Dorothy from the Wizard of Oz or performance artist Marina Abramovic. Perhaps Gagaloo's just looking for a little credit?

See the photos above and below and make your call. Is Katy biting Gaga's signature kooky looks?
