In a Q&A on Twitter, Charli XCX revealed she was supposed to create a 911 remix.
HELL YES. I LOVE chromatica. her best era imo. rain on me was the song of 2020 & I wish the clubs were open when it came out so we could have raaaaved to it. Blood Pop hit me up about doing a 911 remix but nothing came of it, obvz I would have died & done it in a heartbeat. https://t.co/UNtTlSEgo3— Charli (@charli_xcx) March 27, 2021
The singer stated Bloodpop contacted her, but unfortunately nothing came of it.
Bloodpop took to Twitter in response. He posted a DM conversation he recently had with Charli in regards to her tweets. He said they sent the stems of the song to her back in November of 2020; however, there must have been a communication error because Charli claimed to have never gotten them. She said she will look to see if her team has them.
From the conversation, it is possible a new 911 remix may be released soon.
