Dua's a known Kylie stan and has been on record saying 'Slow' is her favorite Kylie song and video, so, how fitting to film in the same gorgeous pool in Barcelona? I think there's even a little 'All the Lovers' tribute in there with the multi-tiered choreography at the end.
The song is pure Dua -- wouldn't have been out of place on Future Nostalgia. BOP!
