‘Downton Diddy’ to be a Self-Fulfilling Prophecy?

Might Lord Wolcott grace the halls of Downton Abbey after all?

Sean “Diddy” Combs had some fun in May with a Twitter hoax that claimed he was joining the cast of the popular PBS costume drama. The tweets turned out to be plugs for “Downton Diddy,” a Funny or Die spoof that starred the rapper-actor-mogul as a previously unknown nobleman named Lord Wolcott, strategically inserting him into key scenes alongside Lord Grantham, the Dowager Couness and the rest.

Among those charmed by “Downton Diddy,” it turns out, was Julian Fellowes, the creator of “Downton Abbey.” On Wednesday the producer told The Telegraph that he “absolutely adored” Diddy’s spoof and was open to giving him a cameo in the actual series.

Mr. Fellowes would never say never to the notion, he said, “though I imagine he’d steal the scene, even if it was a small part.”

No word on whether the appearance would come with underwriting support from Ciroc.
