Diddy may be cocky on his not-so-hit MTV reality show Making the Band, but it looks like Sean "Diddy" Combs doesn't pack the power he once did.

The New York Post is reporting that Diddy has gone from A+ lister to B- lister rather quickly.

HE once ruled the party scene from New York to the Riviera, but it seems Sean "Diddy" Combs' social status is slipping. Sources at St. Tropez hotspot Les Caves - where the rapper was once a regular fixture - told Page Six that when the daddy of four showed up at the club Thursday night, he was refused a table.

"He is so B-List here," said the snitch. "No one even acknowledges him." The second-rate treatment was a steep fall from the days of 2003, when Diddy first landed at the French resort with a full-time entourage that included a personal umbrella carrier named Fonzworth Bentley.

Diddy is known for being unnecessarily cocky and often times extremely rude.  Combs likes to call the shots and rule the roost, but not many B-listers get to act like divas and maintain respect.

Could this be the beginning of the end for the once king of hip hop?!  It appears that way!!!!
