It slayed me on the radio like how E.T. slayed me one and a half year ago. I turned up the volume and googled playlists of radio stations to find it.
They must be inspired by Katy. Very addicted melody lines, dragging/stretching the vocals over de melody lines to make it sound sexy,... Hair colours, classic untanned pale white skin, red lips,... The lyric video like how Katy popularized it with good examples. There are many songs on the radio trying to make Katy-like sounds. This one is the first good one.
And inspired by Adele to increase the power of the vocals. The music also has to keep up with the increased power. Like Wildest Moments, Girl on Fire (Inferno version), Summer Sadness,... already did.
I think that is more like Jade's thing she's a ballet dancer from what I've gathered, I'm sure she can pull it off as well. Actually, I think only Perrie can't. There, I said it. Miss Perrie should just stick to the vocals and let the other girls do the moves.
