Grimes performs during the Hangout Music Festival on May 22, 2016 in Gulf Shores, Ala.

After connecting through Instagram earlier this month, Grimes confirmed earlier this week that she’ll be working with K-pop girl group Loona on an upcoming single, “Love4eva.”

On Sunday, the Canadian artist tweeted that she’ll be lending her “dark chaos magic” to Loona’s next track. The group had previously teased the song, on social media, and announced it officially on May 19.

"Grimes, You are Loona's goddess!" the group wrote on Twitter in response to Grimes' tweet. "It's an honor to work with you."

“Love4eva” will appear on Loona yyxy’s Beauty & The Beat EP, which will be released on May 30. It notably was co-written by songwriting team E-Tribe, best known for Girls’ Generation’s breakout 2009 hit “Gee.”

Grimes and Loona connected after the girl group DM-ed the soloist on Instagram; they asked Grimes to check her direct messages on an image she posted teasing upcoming music with Poppy.

The new song will feature Loona’s yyxy unit, featuring members Chuu, Yves, Go Won, and Olivia Hye. It is the last sub-group ahead of the girl group’s impending formal debut as a 12-member act; since 2016, the act has released multiple singles and albums from members of its group in one of the longest lead-ups to a first album that the K-pop world has ever seen.

“Love4eva” is the 17th single from the girl group, following solo tracks introducing each of the dozen singers as well as a handful of songs performed by groups of three or four members each. yyxy is the third unit, following ? and Odd Eye Circle. The latter’s EP Mix & Match peaked at No. 10 on the World Albums chart last year.

Loona shared a teaser video for “Love4eva” on Thursday, May 24, promising an upbeat electro-pop song. Listen here:
