The two joined forces for Nicki's epic performance to open up the 2015 MTV Video Music Awards.
After appearing on stage for "The Night Is Still Young," Taylor joined Nicki for a brief cut of her own hit, "Bad Blood."
While there is clearly no bad blood with Taylor, the blood might be boiling between Nicki and VMA host Miley Cyrus.
“And now, back to this b***h that had a lot to say about me the other day in the press,” Nicki said, seemingly calling out Miley while accepting her Best Rap Video Award. “Miley, what's good?”
