The excitement surrounding Grimes and her connection to Elon Musk has been whirling around since their Met Gala red carpet debut earlier this month.

Returning to music with the 12-piece K-pop girl outfit Loona, Grimes receives a full feature credit on the utterly infectious "love4eva".

Without detailing what she's actually contributed, Grimes' musical direction and attachment to K-pop is enough to understand her input in the upbeat, punchy pop track.

The neon bright beat is complimented by four yyxy members and their soft vocals, as they dance in co-ordinated outfits in the school inspired visuals.

"love4eva" is taken from Loona/yyxy's Beauty & The Beat EP, which is out now.
