There’s just no shaking off this feud! Taylor Swift’s ex, Calvin Harris, is collaborating with the singer’s longtime nemesisKaty Perry, on his new album, Funk Wav Bounces Vol. 1, due out next month. Before the news broke, the “Bon Appétit” singer warned no one in particular, “You can’t mistake kindness for weakness — and don’t come for me.” We guess Katy and Calvin just want to let bygones be… hit songs!
