Diddy Joining the Cast of Downton Abbey?

Is Diddy joining the cast of the BBC period drama “Downton Abbey”?

On Wednesday, the mogul tweeted, “I have to admit that Downton Abbey is one of my favorite shows- and thats why Im so excited today @DowntonAbbey”.

He later followed that message by writing on Twitter, “MY BIG NEWS: So happy to announce that Im a series regular on DOWNTON ABBEY-my favorite show+i’ll be debuting a sneak peek tonight 12am PST!”

A number of news outlets and blogs fell for it, but it’s “not true,” a spokesperson for the show tells Gossip Cop, reiterating, “He is not joining the cast of ‘Downton Abbey.’”

It’s unclear why Diddy — who also changed his Twitter background to the logo of “Downton Abbey” — claimed he’ll be on the show.
