File this one under “you can’t keep a good man down.”

Fresh off his highly publicized arrest at Hollywood Casino in Maryland Heights, Nelly surprised Machine Gun Kelly by jumping on stage and performing during the annual MGK Day celebration in Cleveland on Saturday.

As TMZ reported last week, Nelly hit a slot machine jackpot to the tune of $50,000 and all heck broke loose.

 A casino security background check came back with a red flag – an outstanding arrest warrant. Driving without insurance came back to haunt Nelly because he failed to address the issue. An arrest warrant had been issued.

Things worsened when police allegedly found four ecstasy pills on his person. After a “perp walk” through the casino, Nelly was carted off to jail.

His famed defense attorney, Scott Rosenbloom said “instead of just supervising the transfer of [Nelly’s] winnings [a police officer] felt compelled to needlessly run a check for warrants.”

He said there was no probable cause for the search and that Nelly “was targeted by an overzealous, out-of-line officer.”

The casino did eventually cough up Nelly’s 50K, according to TMZ.
