Sean “Diddy” Combs’ social status is slipping. The Bad Boy mogul has officially hit D-List status at St. Tropez hotspot Les Caves where he was denied a table last Thursday night.

“He is so B-List here,” said the snitch. “No one even acknowledges him,” chuckles an NYP source.

“Nobody goes out there until the first and second week of August,” says one insider. “Maybe he’s afraid he’ll get lost in the crowd once all the real celebs show up.”
