It's plausible that Gaga didn't know it was her. I doubt she cares enough to shade Katy or even pay attention to her. I think the only feud between these two women is the one fueled by the people who want it to happen. Pulling drama and "shade" out of thin air doesn't really serve a purpose.
Does anyone else just not have a f___ing clue what's going on?
What is that tweet even about? Is it trying to be funny? And if so, what's meant to be funny about it? Like just a big general WTF......
Gaga has said she would fave + reply to people posting their artrave costumes and pictures of them getting ready for artrave. She probably thought it was a legit picture of some.of her fans
