Katy Perry‘s old feud with Taylor Swift is dunzo — something we already knew, but which was double confirmed by the fact KP crashed her Aussie show … and sang a certain song.
The pop star was one of a handful of famous people on hand Friday for T-Swift’s first Sydney concert — where she was hanging in the VIP tent with Rita Ora and, of course, Travis Kelce … who flew on down to be with his girlfriend.
Katy’s presence was interesting though … on account that she and Tay Tay used to beef.
That’s why her singing “Bad Blood” — which has always been rumored to be about Katy — was fascinating to see … as Taylor belted out the tune onstage, she was being recorded singing along down in the crowd. It’s the ultimate irony … and proof they’re all good now.
