We wonder if Katy will respond to Gaga’s not-so-subtle dig at her artistic integrity.

The enigma that is Lady Gaga took to her Twitter account yesterday to call Katy out for copying her: “It looks like green hair and mechanical horses are the thing now.”

While the ARTPOP creator never mentioned Katy’s name, there’s no denying who the tweet was aimed at.

Another Twitter user recently tweeted the comparison between the two pop starlettes after seeing Katy’s Prismatic concert:

While there definitely are similarities, Lady Gaga goes through so many looks and concepts that it’s almost impossible for musicians to try something new that she hasn’t dabbled in at some stage.

But what do you think? Is Katy a kopy-kat or is it pure coincidence?
