Grimes says her new song is about how Azealia Banks 'tried to destroy' her life

• Grimes said her new song was about "having to defeat Azealia Banks when she tried to destroy my life."
• Banks, Grimes, and Grimes' partner, Elon Musk have been involved in a feud since 2018.
• Banks responded in a now-deleted post saying Grimes has a "psychosexual obsession" with her.

Grimes added to the ongoing feud between her, her boyfriend Elon Musk, and rapper Azealia Banks.

On Sunday, the Canadian singer revealed on Discord that one of her new songs, "100% Tragedy," is about "having to defeat Azealia Banks when she tried to destroy my life."

Grimes, her partner, and Banks have been involved in a back and forth since 2018 when the rapper wrote a series of negative tweets about them after spending a weekend at the Tesla CEO's home. According to Banks, she was there to make music with Grimes but was instead left to her own devices as Grimes "coddled" her boyfriend. Banks wrote on her Instagram story at the time that, "staying in Elon musks house has been like a real [life] episode of 'Get Out.'"

Banks responded to the theme of Grimes' new song in now-deleted Instagram stories that were captured by the Daily Mail. She wrote: "Grimes def has some psychosexual obsession with me. I think it's bitterness cuz she doesn't have the musical capacity I have.

"Everything she does is out of pretentiousness and it comes out like that … while everything i do is out of natural swag & geniusness lmaoo."

The rapper also mentioned the subpoena she received regarding the lawsuit filed against Musk in 2018 alleging that the CEO made false and misleading statements when he tweeted that funding was "secured" to take Tesla private at $420 a share in 2018.

She wrote on her Instagram story: "Really thought I did you a favor by not responding to that subpoena. I just may happen to have all those texts/screenshots/evidence laying around somewhere."

Insider has reached out to Banks for an official comment.

Banks received the subpoena because she was at the CEO's house the same weekend that Musk tweeted about the funding. The rapper told Insider in 2018: "I saw him in the kitchen tucking his tail in between his legs scrounging for investors to cover his ass after that tweet."

Musk originally denied that he met the New York rapper, telling Gizmodo that he did not meet or directly communicate with her. However, he later told The New York Times that he saw her "for two seconds at about a 30-foot distance as she was leaving the house."

In August that year, Banks did post an apology letter to the CEO on her Instagram story saying: "What started off as a cat-fight lead to some seriously unexpected consequences and I seriously apologize."

She also said that she did not want to get involved with the lawsuit following her subpoena. "The first round of Elon Musk bulls--- was stressful enough," She told Insider, "I don't have the bandwidth for another row with him."
