"Famous" features background vocals and guitar from John Mayer. Ty Dolla Sign recruited the singer-songwriter for the tune through Instagram. He explained to Billboard:

"He hit me up when I posted the 'Love U Better' single artwork, and said the artwork was dope. So I hit him back, and said, 'I wanna come to your concert when you come to LA,' and he said, 'Sure, hit my tour manager and he'll get you situated or whatever.'

So we did, and that show was so dope that we went to the Anaheim show. So we went to that as well, and then the next day I was in the studio, I was like, 'If you're still around, pull up.' And he was, and he pulled up solo, no cameras, no security guards, nothing extra, just on the music. And I had a feeling that he might not have a guitar on him, so I had rented one and had it ready to go."
