Beautiful Girls” hit maker Sean Kingston is singing the blues after a jeweler filed a lawsuit against him.

TMZ reports that Norman Silverman Diamonds claims Kingston paid$10,000 up front for a Rolex watch in June of 2013. NSD alleges the singer’s check for the $36,000 balance bounced.

In September of 2013, the jeweler managed to get Kingston to pay another$15,000 towards his debt, but hasn’t been able to reach him since.

Silverman finally got fed up and is suing Kingston for the $21,353 balance, plus damages and lawyer fees.
