We're picking up a scent of “Bad Blood,” but this time it's coming out of a perfume bottle.

Katy Perry and Taylor Swift's rumored feud, which began when the “Style” songstress claimed that an unnamed pop star (believed to be Perry) stole dancers from her tour, might have reached a new level thanks to Perry's new perfume. Called Mad Love, the new perfume has people believing that it's a direct reference to Swift's “Bad Blood” because of the same wording.

“You know it used to be mad love,” Swift sang in the song, also rumored to be about her ongoing feud with the “Roar” singer.

Mad Love is meant to be a spinoff of Perry's 2015 scent, Mad Potion, so it's entirely possible that it's just a coincidence. Swift, 26, opened up about the feud to Rolling Stone magazine in 2014 when she called out an anonymous artist for trying to sabotage her and her tour.

“For years, I was never sure if we were friends or not. She would come up to me at awards shows and say something and walk away, and I would think, ‘Are we friends, or did she just give me the harshest insult of my life?'?” she recalled to Rolling Stone. Then last year, the other star apparently crossed a line, according to Swift. “She did something so horrible, I was like, ‘Oh, we're just straight-up enemies.' And it wasn't even about a guy!”
