Proving that a showbiz feud is nothing if not bitter, Katy Perry and Taylor Swift appear to be - STILL - at loggerheads.
Ms Perry, 32, has today released her much-anticipated new album,
Witness.
It includes hits such as
Chained To The Rhythm and
Bon Appétit and has fan all-sorts of excited as it's the star's first album since
Prism FOUR years ago.

So far, so standard, you say.
However, in an intriguing twist a certain Taylor Swift - she of the long-running feud with Katy - has made a pretty spectacular announcement of her own.
Yes, after years of refusing to put her music on Spotify, Tay-Tay last night released ALL of her albums onto the world's leading music-streaming platform.
Coincidence? Probably not (though we'll let you be the judge).

There was no promotion of this milestone move by Ms Swift, nor does Thursday, June 8 seem to have any real significance for her.
Still, predictably Twitter has been having a field-day in the aftermath.
Promoting
Witness, Katy has been chatting about her dispute with Taylor (we won't go back into the nitty-gritty - something about one of them/both of them 'stealing' dancers for a world tour).
Referring to 'the incident,' Ms Perry told James Corden last month: “That’s true, there is a situation. Honestly, it’s really like she started it and it’s time for her to finish it.
"I’m not Buddha – things irritate me," she continued.
"I wish that I could turn the other cheek every single time, but I’m also not a pushover, you know? Especially when someone tries to assassinate my character with little girls. That’s so messed up!"
