You wonder why Taylor Swift has been radio silent about her old drama with Katy Perry… Even after Katy has released the “Swish Swish” response track to “Bad Blood,” and addressed it on Carpool Karaoke?

T-Swift is over it… Let’s just say, that feud is so 2015.

According to Us Magazine, T-Swift “honestly wants no part of this, that’s why she avoids talking about it… She doesn’t want to engage.”

Katy did tell James Corden and SiriusXM Morning Mash Up that she’d be willing to reconcile with T-Swift if she received a text or a FaceTime call, saying “I am ready because I think when women unite, the world is going to heal.”

And who knows, maybe T-Swift sent her a text or something, but she’s definitely done discussing the drama in public.

Even though Taylor’s biggest success has been 1989, it seems she doesn’t like living in the past.
