Trouble seems to follow R&B singer R. Kelly. The man who "put the 'R' in R&B" is being sued by promoter Royalty Records for failing to appear at a scheduled performance. Royalty Records claim that Kelly was originally due to take the stage at Minneapolis' Target Center on December 6, but changed the date to December 20.

When the singer failed to appear in court on December 19, an arrest warrant was issued and Kelly was forced to cancel the Minneapolis show in order to make it to court in Chicago. Royalty Records is looking to recover the $120,000 fee they paid to Kelly and unspecified damages.

This isn't the first lawsuit surrounding Kelly's 'Double Up' tour. R&B sensation Ne-Yo slapped Kelly with a $735,000 lawsuit on December 31. Ne-Yo claimed he was kicked off the tour because he was upstaging the singer and filed the suit requesting he be paid what he was set to rake in.

In the meantime, Kelly's trial for his child pornography case will begin on May 9.
