I think his Kylie collab was cute but not great, but my caveat was with the song itself, it needed a better chorus and an epic bridge to really take it to the next level IMO. The production was

I hope she ends up on his album. Her tendency of not releasing collabs is so frustrating.

The idea of Kylie, Britney and Gaga all on the same album is so perfect.

Giorgio seems to have the same taste in pop girls as me.
