Probably...

The Katy Perry and Taylor Swift feud is the biggest showbiz fight that we rarely talk about… until someone throws some serious shade. Like KP here, who’s released a new perfume called ‘Mad Love’. Eeek!

The whole argument began with Tay-Tay claimed that a certain unnamed popstar ‘stole’ dancers from her tour – and then she released Bad Blood, which we’ve all pretty much guessed is about the Roar singer.

Now in return it looks like she’s pinched a lyric to the shady song for her own lyric – the second line of the chorus is ‘You know it used to be mad love.’

While Mad Love is supposed to be a spinoff of her 2015 version called Mad Potion, it’s not a stretch to assume this was targeted shade.

Opening up about the feud, Taylor Swift told Rolling Stone in 2014: ‘For years I was never sure if we were friends or not… I would think, “Are we friends, or did she just give me the harshest insult of my life?”’ Before the, ahem, mystery other star seemed to cross a line last year:

‘She did something so horrible, I was like “Oh, we’re just straight-up enemies.” And it wasn’t even about a guy.’

You could say that they have… bad blood.

Both stars have sent equally cryptic messages on social media, especially KP’s very poignant: ‘Watch out for the Regina George in sheep’s clothing.’

Then Taylor made the epic song ‘Bad Blood’ with her entire gang in the music video, and she later cleared up that the whole thing was about a ‘lost friendship.’

But now it’s Katy Perry’s turn to hit back in their weird, multi-media war, probably, with this probably shady, shady piece of marketing.
