In the clip, Elon is seen attending one of Kanye‘s shows and chatting with the rapper backstage. While talking, Elon takes the time to pry about his relationship with ex-wife Kim Kardashian.

“So are you and Kim like off and on or something? Or, I don’t know, it’s hard to tell,” Elon asks in the clip. He’s next shown opening up about his own relationship with Grimes, whose real name is Claire Boucher.

“Claire and I, Grimes, we’re sort of … you know, in the same text stream, she’s like, ‘I love you.’ And then, like, you know, a day later, like, ‘I hate you,’” Elon reveals to the rapper.

Despite his own public relationships and breakups, Kanye admits in the clip that he can’t help Elon work things out with Grimes. He tells the tech billionaire, “I don’t have answers. Answers to everything except for that.”

If you didn’t know, Elon will be featured as a character in an upcoming movie about AI.
