Taylor Swift's feud with Kanye West has been in the news lately, but her feud with Katy Perry is still going strong.

Katy Perry's new perfume is called Mad Love, which seems to be a reference to Swift's song "Bad Blood," which is not-so-secretly frenemy history with Perry featuring the chorus, "baby now we've got bad blood / you know it used to be mad love."

The only shocking thing about this is that Swift never registered a trademark for the phrase. 

When "Bad Blood" was dominating the airwaves last summer after a truly exhausting video rollout, Perry tweeted some expert shade.

And now she's capitalizing off of another woman capitalizing of the takedown of a woman (her). Two wrongs may not make a right, but they sure can make a lot of cash. No one will be surprised when Calvin Harris inevitably produces tacks on Perry's Prismfollow up. 

The fragrance, a follow up to 2015's Mad Potion, is currently available for purchase. It smells like "luscious fruits, woods and musk" -- so basically a very, very shady forest. 

For the sake of pop star conspiracy theories, let's assume that this petty branding is a direct response to Tay trying to sabotage Perry's relationship with Orlando Bloom. 

Sure, there's not actually any proof that Swift sent her bestie Selena Gomez to hook up with Bloom at a nightclub in Las Vegas shortly after Perry, Bloom and their matching Tamagotchi children made their first public appearance together at the Met Gala that Swift co-hosted. But it's simply too coincidental to not at least engage in rampant speculation. 

Now Perry's perfume bottle is basically an urn for their dearly departed friendship -- R.I.P. Mad Love.
