Joining the ranks of celebrity-owned restaurants who have received less than perfect Health Department grades is Justin Timberlake, Breaking Celebrity News is exclusively reporting.

The crooner's barbecue joint in New York City, Southern Hospitality, was slapped with a 'B' grade by the New York City Department of Health during a routine inspection on June 19, 2013.

Justin, 32, is a Co-Creator and Creative Consultant of the NYC restaurant, along with best friends Trace Ayala and Eytan Sugarman.

Located in the Hell's Kitchen district of the city, the popular restaurant was docked 22 points by the Department for various violations, which they can challenge and successfully change to be issued a higher grade.

As Breaking Celebrity News exclusively reported earlier this month, the NYC restaurant owned by Lady Gaga's father, Joe Germanotta, had just received an 'A' grade from the health department — so guests at Joanne Trattoria were shocked to see rodents roaming around tables inside the eatery and in the patio area of the Central Park-adjacent establishment on the evening of July 31.
