Las Vegas' "Diddy Day" turned into "Dud Day" as the man of honor, Sean "P. Diddy" Combs, was a no-show.

Due to cited "miscommunication," P. Diddy blew off an event set to honor him with his own day. As previously reported, the event scheduled for Friday (April 15) at the Aladdin hotel-casino, would have seen Mayor Oscar Goodman proclaim the day "Diddy Day."

But it all came to a screeching halt when the hip-hop mogul sent word he couldn't attend.

"Due to an unfortunate miscommunication, I will not be able to make the anticipated trip to Las Vegas on April 15," Combs said in a statement. "I am flattered the mayor saw fit to honor me with a day and hope to join him soon."

Billed as part-ceremony and part-announcement, the event alluded to business venture plans Combs has been working on.

According to AP Press, Las Vegas businessman and producer David Saxe said he and Combs discussed developing a nightclub and "other P. Diddy-related ventures," including a restaurant in the V Theatre, but those plans have since been put on hold.

"I am looking forward to speaking with P. Diddy and seeing what the future may hold for him as far as Las Vegas ventures go and hope to host him in Las Vegas soon," the mayor said in a statement.
