The feud between Taylor Swift and Katy Perry has been ongoing for actual years now.
However, Katy has always remained pretty ~cryptic~ about the fallout. When Taylor implied "Bad Blood" was about Katy, Katy simply responded with this tweet.
In fact, Katy has never straight-up addressed the "Bad Blood" saga – and the closest we came to a confirmation that the drama was about Katy was when Calvin Harris tweeted this during a meltdown about Taylor.
And when Kim Kardashian released those now-infamous Snapchats, Katy's apparent response was also low-key.
However, last night Katy Perry attended Kanye West's LA concert. Of course, he played "Famous."
The song opens with the lyrics that ignited the fued between Taylor and Kimye: "I feel like me and Taylor might still have sex / Why? / I made that bitch famous."
And it seems Katy used the opportunity to be more direct with her shade. She Snapchatted herself pulling faces as Kanye rapped the famous lines.
It's not the first time "Famous" has been used to shade Taylor after SnapchatGate – Kim also snapped herself looking pretty smug as the song played during a night out.
