Grimes

Claire Elise Boucher, professionally known as Grimes, is a Canadian singer-songwriter, producer and director. She is a former friend of Poppy's. She collaborated with Poppy on the song "Play Destroy" from Am I a Girl?.

Relationship with Poppy
In an interview with NME, Poppy said that her relationship with Grimes began when Grimes followed her on Twitter. Poppy then direct messaged her "hi, I like you. We should make a song together". The two later met up and recorded music together.

Poppy made "a couple of songs" with Grimes, confirming that one song would be about destroying things and another would be about power. These songs were later revealed to be "Play Destroy" and "We Appreciate Power", respectively. However, the latter song was instead released by Grimes, featuring American singer-songwriter HANA.

Shortly after the release of "We Appreciate Power", Poppy revealed in an interview with Billboard that she was "bullied into submission" by Grimes, and that Grimes prevented the release of the song on its planned release date months before the release of Am I a Girl?. Poppy further claimed that Grimes also bullied songwriters into signing non-disclosure agreements and did not take credit for songs that they were a part of. Chris Greatti, a close friend of Poppy's, had confirmed that it was in fact written by Grimes, HANA and himself.

On January 28th, 2021, during a YouTube livestream, a fan had asked Grimes how she felt about Poppy after parting ways with Titanic Sinclair. Grimes responded to the fan saying "PROB SHE IS NICER NOW. WE HAVENT SPOKEN BUT I SUSPECT THAT WAS THE ISSUE." On February 9th, 2021, Grimes followed Poppy's former fiancé Ghostemane.
