Social media sensation Fatboy SSE is getting sued by the Mount Vernon school district – along with the city’s embattled mayor – for allegedly sparking a riot that caused more than $76,000 in damages at the local high school.

Fatboy, 26, a Harlem-born rapper and comedian whose real name is Tariq Thomas Kimbrough, was invited to the school by Mayor Richard Thomas on Jan. 11, when the hefty entertainer was “Mayor for the day,” according to The Journal News.

Unfortunately, the district says the mayor never checked with them first.

Thomas and Fatboy were part of an entourage of 14 who popped up at the school and “created a major disruption,” district lawyers claim in a complaint filed in state Supreme Court in White Plains.

The suit said Thomas “walked through the high school hallways, opened classroom doors, informed students that defendant Kimbrough was in the building and irrationally encouraged students to leave class and congregate around” Thomas and the entertainer – even though midterms were underway.

The riled-up students ended up damaging classroom doors and even a glass trophy case, schools officials claim.

The district said the bill for repairing the damage will be at least $76,350.

The mayor apologized shortly after the costly visit, The Journal News reported, and said he had tried to contact school officials a day earlier but was unsuccessful.

Thomas, who is completing his final term as mayor, has already been under fire after pleading guilty to charges that he misused campaign funds during his 2015 mayoral bid.

The mayor’s plea deal gave him until Sept. 30 to leave office, but the Mount Vernon City Council instead named council president Andre Wallace as asking mayor – although Thomas has refused to step down, causing a bizarre standoff.
