The performance begins at 0:19. Ariana is magnificent at imitating the voices of various singers, and this is well known. I know they admire each other; about ten years ago, Katy called her "the most beautiful voice of this generation," and she also attended the One Love concert following the Manchester attack to support Ariana, who was going through a real trauma at the time. So it would be really nice if they collaborated on a song.

The only thing that bothered me a little is this constant reference to space travel (Ariana, in fact, wears a spacesuit and adapts the chorus of "Firework" to the space theme). Even more than eight months after the launch, Katy continues to be the target of pranks and teasing, despite the fact that there were five other women in the capsule (not least, in the series "Emily in Paris," a reference to that episode is made in one scene). The other female passengers weren't even considered at all, except perhaps Gayle King in the first few days, but then not even that much. I can't take it anymore.
