Although neither man looks particularly thrilled to be there, West shared the photo captioning it: "When you go to your boy's house and you're both wearing orange."
In the photo Musk can be seen wearing a black ensemble, with a little orange on the chest of his t-shirt, while West has opted for a more colourful get-up in black trousers, printed t-shirt and a jacket so orange my eyes can't fully register it.
Both fellas are wearing a pair of Yeezys - the trainer brand owned by West - Musk had on a pair of Yeezy 500 Highs while West wore the newly released Yeezy Quantum Barium.
In the reflection behind them you can see Musk's other-half, and mother to his youngest child, Grimes - real name Claire Elise Boucher - taking the photo.
Musk has long been a fan of West. Writing in Time magazine's list of 100 most influential people all the way back in 2015, he heaped praise on the rapper writing: "Kanye's belief in himself and his incredible tenacity - he performed his first single with his jaw wired shut - got him to where he is today. And he fought for his place in the cultural pantheon with a purpose."
He continued: "Now that he's a pop-culture juggernaut, he has the platform to achieve just that. He's not afraid of being judged or ridiculed in the process. Kanye's been playing the long game all along, and we're only just beginning to see why."
West has repaid the compliment, praising Musk's Tesla in a 2018 tweet, in which he said: "I really love my Tesla. I'm in the future. Thank you Elon."
I really love my Tesla. I'm in the future. Thank you Elon.

And who can forget the time he hopped onto a table at Detroit's College for Creative Studies and told the students to leave Musk 'the f*** alone'?
In a clip from 2018, West can be seen stood on a desk telling the gathered students: "Elon Musk? I don't care who's over at his house, leave that man the f*** alone. Leave that man the f*** alone."
I think we're looking at a long and beautiful bromance here, guys.
