Nelly lives out his dreams in the inspirational video for “The Champ,” his triumphant tune created for ESPN’s Bowl Week. The St. Louis rapper, who almost pursued a professional career in baseball, plays a football player who gets pumped up for the big game. He takes to the field and locker room as a marching band provides the soundtrack to his anthem. Taste the victory.

Nelly paid a visit to music’s resident doctor, Dr. Dre. The St. Louis rapper hit the studio for a late-night recording session with the West Coast icon on Monday, tweeting a photo from the lab.

“WOW in studio wit the legend dairy @drdre,” shared Nelly, who released his mixtape O.E.MO on Christmas Eve.

Nelly is working on the follow-up to 2010’s 5.0. Meanwhile, Coachella headliner Dre has decided to take a break from recording his long-awaited Detox.

Over the holidays, Bei Maejor’s remix to “Trouble” hit the net featuring Wale, Trey Songz, T-Pain, and J. Cole. Now Nelly reveals himself as the fifth guest, who Bei Maejor first hinted about on “106 & Park.”

“This is the dean of the university of bosses, I need all the bad bitches to report to my office,” raps Nelly on his closing verse.

Get into some more trouble with the whole gang.

In the spirit of the season, Nelly drops his free mixtape O.E.MO (On Everything MO). The country boy raps and sings over popular songs including Drake’s “The Motto,” T-Pain’s “5 O’Clock,” and Machine Gun Kelly’s “Wild Boy,” with appearances from the St. Lunatics and Bei Maejor.
