Elon Musk and Grimes whose real name is Claire Elise Boucher, have broken up after remaining together for three years. The couple also have a child together.
'We are semi-separated but still love each other, see each other frequently and are on great terms,' Musk said, reports the Daily Mail.
The billionaire confirmed that he and the electronic pop singer are 'semi-separated' but plan to co-parent their 1-year-old son, according to Page Six.
The SpaceX and Tesla CEO explained, '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 A-list couple were spotted together a few weeks ago when they attended the Met Gala. Grimes walked the red carpet alone and met Musk inside.
After the gala, Musk hosted an exclusive afterparty with Grimes at club Zero Bond.
Musk and Grimes were first reported to be dating in May 2018 and welcomed their first child together in May 2020. Musk has fathered six other children.
The couple's child was named X Æ A-Xii (name pronounced Ex Ash A Twelve), but has been nicknamed X. The 33-year-old singer recently revealed that her child never calls her 'mom' and inspired new creativity in her.
'I think having a baby was a big rebirth for me artistically. Being a mother feels weird for me to say,' Grimes began.
'X says Claire, but he doesn't say 'mama'…like, maybe he can sense my distaste for the word 'mother,'' she added.
As Musk mentioned in his explanation of his split with Grimes, he recently relocated to Texas after nearly two decades in the Golden State. Musk confirmed his move to Texas in December 2020 following a feud with California lawmakers over government shutdowns amid the COVID-19 crisis.
In the summer of 2020, the Musk Foundation officially consolidated its headquarters in Austin - a city that also houses a Tesla assembly plant. However, Musk is also known to spend time in Boca Chica, on the southeast coast of the state, where there is a SpaceX facility.
Two months after welcoming baby X, Musk admitted that Grimes held the majority of the parenting responsibilities saying that she 'has a much bigger role than [him] right now.'
'Well, babies are just eating and pooping machines, you know? Right now there's not much I can do,' he told the New York Times. 'When the kid gets older, there will be more of a role for me.'
His July 2020 interview came a day after Grimes posted and then deleted a tweet scolding her partner for a tweet about pronouns.
'Pronouns suck,' Musk tweeted shortly after writing 'Twitter sucks.'
She responded: 'I love you but please turn off ur phone or give me a dall [sic]. I cannot support hate. Please stop this. I know this isn't in your heart.'
Musk has been married three times before; once to author Justine Wilson, with whom he has five sons: twins Griffin and Xavier, 17, and triplets Damian, Saxon and Kai, 15, and twice to 'Westworld' actress Talulah Riley.
They tragically lost their sixth child when the 10-week old died from SIDS.
The couple first wed in 2010 but divorced in 2012. They tried again a year later, and were remarried in 2013 but divorced again in 2016.
