We probably don’t need to remind ourselves that the two pop stars – Katy and Taylor – have been feuding for years. However, their feud ended a while ago with a sweet gesture. A week after they declared “finally peace”, Katy appeared as a guest in Taylor’s “You Need to Calm Down” video.

On the latest episode of American Idol last night (US time), after two female contestants performed an excellent duet, Katy declared “that’s what queens do”.

Katy then chatted with her fellow judges after the contestants left the stage and she said: “Can you imagine if me and Taylor worked together, what we could do? ?”.

The video is going viral on Twitter as fans are excited about the possibility of the two stars collaborating on a song.
