Katy Perry held no grudges on her ‘Witness’ album by teaming up with songwriting supremo Max Martin – co-author of her rival Taylor Swift’s hit ‘Bad Blood’ – for several songs.
That track is a diss to Katy, after she poached three of Taylor’s backing dancers to join her ‘Prismatic World Tour’ in 2014.
Katy said: "He didn’t know [who ‘Bad Blood’ was about]. I’m not supposed to tell him what he can and can’t do. I’m very fair; I’m super-duper fair … and I love Max. I’ve been working with him my whole career."
