 It's now red-carpet official: entrepreneur Elon Musk, 45, and musician Grimes, 30, are an item. 
  
 The South Africa-born billionaire (who moved to Canada when he was 17) and Canadian artist arrived at the Met Gala together on Monday, confirming reports that two have been quietly seeing each other.

 Did they dress for the carpet theme, "Heavenly Bodies: Fashion and the Catholic Imagination"? Yes, if you consider Musk's electric cars heavenly bodies: He appeared to wear a Tesla pin and she a Tesla choker as part of their coordinated ensembles. 
  
 The unlikely couple got connected after they made the same artificial intelligence joke, reports Page Six. As the story goes, Musk, a longtime A.I. warner, thought of a pun that's way over our heads and combines A.I. thought experiment Roko's Basilisk with baroque European style Rococo, to make "Rococo basilisk." 
  
 But Musk realized Grimes had made the same highbrow A.I. joke, years before he thought of it. So, according to the report, he reached out to her (before finally tweeting out his pun today) and they got together. USA TODAY has reached out for confirmation on this story.

 “They have been dating for about a month,” another source tells Us of the new couple. 
  
 The source added that pair designed the musician’s dress together over dinner and commissioned a team to make it. 
  
 Musk, 46, tweeted about Grimes’ music in April. “Likewise …was just listening to Go Flex & Psycho on @Grimezsz playlist,” he wrote on April 25. 
  
 “glad ur finally listening to cyberpunk speedwae hahaha,” the 30-year-old replied. 
  
 After the duo exchanged tweets, a fan tweeted at Musk on April 27 to “just ask her out already.” He responded with a wink face. 
  
 Us Weekly confirmed on February 1 that Musk had called it quits with on-again, off-again girlfriend Amber Heard. 
  
 “Amber wants her independence and prefers being friends rather than romantically linked,” one source told Us at time.

 Perhaps the most unexpected couple made their debut at the 2018 Met Gala when Elon Musk and Grimes appeared together on the red carpet. 
  
 The Space Exploration Technologies Corp. (SpaceX) CEO/Tesla co-founder and the musician (real name Claire Elise Boucher) have been flirt-tweeting back and forth for a while, and reportedly met when Musk discovered Grimes beat him to a “Rococo Basilisk” joke on Twitter. 
  
 The two were dressed in black and white for the “Heavenly Bodies: Fashion & the Catholic Imagination” theme, a topic that heavily contrasts with their interest in artificial intelligence and technology. 
  
 A version of this story originally appeared on Billboard.com. ||||| Elon Musk has been keeping everyone guessing about his love life, but sources exclusively revealed to Page Six that he has been quietly dating hip musician Grimes — who will walk the red carpet with him at Monday’s Met Gala. 
  
 A source tells us the pair met around a month ago online, of course, through a joke Musk had planned to tweet but discovered Grimes had already made, dealing with the complications of artificial intelligence. 
  
 Thought experiment Roko’s Basilisk considers the hypothesis of a future where AI lords over the world and could punish those who did not help it into existence. His joke was to merge this thought experiment with a pun using “Rococo,” referring to the ornate French 18th century baroque style, perhaps pointing out that both concepts are complex, too extreme and ridiculous. 
  
 And while this takes some explaining, arty performer Grimes was already in on the same joke — three years ahead of Musk. 
  
 In 2015, she created a character named “Rococo Basilisk” for a video of her song “Flesh Without Blood.” “I don’t know if you’ve heard of Roko’s Basilisk,” she told Fuse. “[This character] is doomed to be eternally tortured by an artificial intelligence, but she’s also kind of like Marie Antoinette.” 
  
 “Elon was researching the idea of joking about Rococo Basilisk, and when he saw Grimes had already joked about it, he reached out to her,” says the insider. “Grimes said this was the first time in three years that anyone understood the joke. They were both poking fun at AI.” 
  
 Musk is well known for warning of an AI apocalypse, calling it “more dangerous than nukes.” 
  
 SpaceX and Tesla founder Musk has been very public in his past fandom for Grimes, whose real name is Claire Boucher. He tweeted out her artsy video with Janelle Monae for the song “Venus Fly” this past March, adding “Best music video art I’ve seen in a while.” 
  
 Grimes shot to fame in 2012 with her third studio album, “Visions,” and also put out the critically acclaimed “Art Angels” in 2015. She recently revealed she has clashed with her label 4AD, saying “There’s some srsly f–ked up and crazy s–t going behind the scenes in my career,” but that she will be releasing another album with 4AD, followed by independent music. “I just took a month off, a lot of insane s–t went down and I’m reorienting my life,” she wrote on Instagram. “I have a deep well of s–t this time, like sooo many songs so after my album I’ll be able to consistently release new music.” 
  
 She was a double major in psychology and philosophy, with minors in Russian and electro-acoustics before she dropped out of school to follow her music career. 
  
 The tech billionaire also tweeted his approval of her Spotify playlist “Go Flex & Psycho.” “Glad ur finally listening to cyberpunk speedwae hahaha,” she responded. “Sounds great riding my cyborg,” he hit back. 
  
 Just last week they had another online in-joke. After Musk tweeted a video created from long-exposure photos of a comet, Grimes said “that’s a lot of cocaine,” to which he responded, “Yeah, most people don’t know this, but comets [are] mostly made of cocaine.” 
  
 Aside from flaunting their banter online, Musk hinted at his talented Met Gala date on Monday, tweeting “Rococo basilisk,” and a link to the Rococo Wikipedia page. |||||
Output:
The Hollywood Reporter calls them "perhaps the most unexpected couple" to show up at the Met Gala on Monday evening, and Elon Musk and Grimes certainly caused some buzz on the red carpet. Now people are wondering if the SpaceX/Tesla founder, 46, and 30-year-old Canadian musician are an actual romantic item, and sources tell Page Six they are indeed "quietly dating." They reportedly first connected over a joke about artificial intelligence Musk had wanted to post on Twitter—until he discovered Grimes (real name Claire Elise Boucher) had tweeted out the same joke in 2015. "Grimes said this was the first time in three years that anyone understood the joke," one source says. USA Today reports they both apparently wore Tesla accessories to the Met event: she a Tesla choker, he a Tesla pin. Meanwhile, a source tells Us Weekly that the couple, who've been canoodling for a month or so, worked up the design for Grimes' Met dress together, then pulled together a team to create it. Musk previously dated actress Amber Heard.
