According to Fox News, the 33-year-old Canadian singer, whose real name is Claire Elise Boucher, split from the billionaire Tesla founder in September after three years together. They share one son together, names X AE A-Xii or 'Baby X'.
In the song, she sings, "I'm in love with the greatest gamer. But he'll always love the game more than he loves me."
Before starting the electric vehicle company, Musk developed video games and considers himself an avid game who still loves to play 'Halo'.
Elsewhere in the song Grimes sings, "Sail away to the cold expanse of space, even love couldn't keep you in your place."
Musk also founded SpaceX, an aerospace manufacturer and space transportation company, in the hopes of colonizing Mars one day.
When the entrepreneur and the songstress split three months ago, Musk told Page Six at the time, "We are semi-separated but still love each other, see each other frequently, and are on great terms."
He said, "It's mostly that my work at SpaceX and Tesla requires me to be primarily in Texas or traveling overseas and her work is primarily in LA. She's staying with me now and Baby X is in the adjacent room."
The couple was last seen together at the 2021 Met Gala in New York City. Grimes walked the red carpet solo and met up with Musk later inside the event. After the fashion party, they threw a star-studded after-party at the private club Zero Bond.
Musk was previously married to author Justine Wilson from 2000 to 2008, and they share twin sons Griffin and Xavier and triplet sons Damian, Saxon and Kai. They also had a sixth son, Nevada, who died at just 10 weeks old.
After Wilson, Musk married and divorced actor Talulah Riley twice. The first time was from 2010 to 2012 and then again from 2013 to 2016.
As per Fox News, meanwhile, Grimes was in a previous relationship with electronic musician Jaime Brooks from 2012 to 2018.
