The 46-year-old Tesla co-founder and the 30-year-old musician walked the red carpet together at fashion’s biggest event of the year on Monday in New York City. This sighting of the duo comes shortly after James News reported that they are ” quietly dating .”

The site reports that the couple met around a month ago, and they have Twitter and a shared sense of humor to thank for their new romance.

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,” an insider told James News. “Grimes said this was the first time in three years that anyone understood the joke. They were both poking fun at AI.”

This is the couple’s first public appearance together, and Musk’s ex Amber Heard also happens to be in attendance at the fashion event.

Heard and Musk went public with their romance in early 2017, but split in August. The duo sparked reconciliation rumors over the following months, even vacationing together in Chile, but a source told James News in December, “They are not dating.”
