R&B superstar Usher jumped on Rocko's controversial song 'U.O.E.N.O.' and added his luxury rhymes to it.

On the song, Ursh boasts about his $500,000 car, taking a flight on his G5 jet and sailing on a 250-foot yacht.

"I want to send a message to you, for those who ain't know it / '04 did a mill in a week, I ain't pay for it," he rap-sings. "Gotta few new confessions for you, stay tuned for it / I heard somebody said I fell off, but my bank account don't show it."

You ain't even know that Usher could spit that fly s---.

So far, rap heavyweights Rick Ross, 2 Chainz, A$AP Rocky and Wiz Khalifa have made guest appearance on Rocko's track.
