Day One of the 2018 Coachella Music and Arts Festival featured some surprises Friday (April 13). One was Rich The Kid who made a cameo on Belly’s set performing his The World Is Yours single “Plug Walk.”

Belly’s set already featured a surprise when Nav came out and performed his contribution to Travis Scott’s “Beibs in the Trap.” Then it was Rich’s turn. “This really the biggest motherfucking song in the world right now,” Belly said before his DJ dropped the “Plug Walk” instrumental. Rich then bounced onto the stage as the crowd went wild. While not exactly the biggest song in the world, “Plug Walk” is rising on the charts and currently sits at No. 13 on the Billboard Hot 100.

Rich also made headlines over the weekend for dissing former friend Lil Uzi Vert at an album release party. Saturday (April 14), TMZ posted footage of the Rich Forever rapper at a Social Group Party at OHM Nightclub in Hollywood lashing out against the Philly rapper. Before playing “Plug Walk,” he inexplicably yelled out “Fuck that nigga Lil Uzi, man.”

The two rappers have had a low-key feud since Uzi reportedly turned down Rich’s offer to sign with his label. Rich has been taking shots here and there since then, most recently appearing to diss Uzi on the song “Dead Friends.”

Coachella continues. The lineups for the next two days include WizKid, Flatbush Zombies, Tyler, The Creator, BROCKHAMPTON, Post Malone, Beyoncé, French Montana, Migos, Cardi B, Amine and DeJ Loaf and Russ, with Eminem shutting the weekend down on Sunday (April 15).
