Let's get right to it. Katy Perry — I love her to death, I really do — but she has a history of shading people. Sometimes it's accidental, sometimes it's intentional, sometimes you just can't tell.
She specifically has a history of referencing Britney Spears' 2007 public breakdown. Like here in 2015:
In one radio interview she said, "It's like being No. 1 and being hot is a lot to live up to. I'm gonna shave my head next year. I can't handle the pressure...beating up your car with an umbrella."
And in 2017, she made ANOTHER joke at the Grammys:
Well on Friday, she posted this picture of a Q&A with producer Greg Wells. Wells praises Katy Perry by dissing Britney Spears, saying people "think [Katy Perry] is handed a script like a Britney Spears and told what to sing. It's the exact opposite."
Wells said, "She is telling people like me or [producer] Max Martin what to do. She tells her management who will direct her video and she tells her label what he first single will be. She drives it. She's been like that since the first album."
Fans were not happy Katy posted and praised the quote on her story because it implied Britney didn't do any of the above mentioned:
But fans soon came with receipts that showed Britney does do all of what the producer said she didn't:
In conclusion, I don't wanna take sides, but I'll say this: Both are talented, both are amazing, both WORK HARD and DO a lot!
