A spoof video splicing Downton Abbey footage to make its actors 'perform' One Direction's What Makes You Beautiful has had 86,000 hits.
The winners of the Screen Actors Guild Awards have been announced, with more success for Brits Daniel Day-Lewis, and the Downton Abbey cast.
British stars have been honoured at the Golden Globes with Adele, Dame Maggie Smith and actor Damian Lewis all collecting gongs.
Yesterday, Diddy, 43, caused a social media frenzy after he announced his "big news" that he was joining his "favourite show".
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!From @iamdiddy on Twitter:
However, he cleverly wrote Downtown rather than "Downton" Abbey which he had mentioned in a previous tweet.
Many people took to Twitter to congratulate him on his "casting" on the British period drama, while others thought his account may have been hacked.
It prompted a response from a spokesman for PBS, who broadcasts the show in the US, who told Reuters the claims were "not true".
Julian Fellowes' Downton Abbey has been a huge hit Stateside, winning numerous accolades including a Golden Globe and an Emmy Award.
The fourth series is currently being filmed in the UK.
The creator of Downton Abbey Julian Fellowes is confident Shirley MacLaine will return to the show in the future. The Hollywood star played the Countess of Grantham's mother, Martha Levinson. Fellowes said: "She will come back, I'm sure."
Viewers will also see new mother Lady Mary Crawley as a widow after the shock death of her husband Matthew during the Christmas special:
"I was very, very sorry Dan left. I thought he did a terrific job for us, I think he's a terrific actor. But actually, nothing is harder to dramatise than happiness. When two people are happy, that's it.
"That's why in the old movies, they don't kiss and marry in the middle, they kiss and marry at the end, because in a way that's it.
"So now we've got Mary widowed, trying to control the estate, feuding with various other people about what the right way forward is, looking for a new life, dare one say it. All of that is really more interesting than two people sitting by the fire having a cup of tea."
Downton Abbey star Dame Maggie Smith has won the Golden Globe Award for Best Supporting Actress in a TV series:
Some of the British stars nominated for Golden Globe Awards have started arriving on the red carpet.
Downton Abbey star Michelle Dockery is up for the Best Actress in a TV drama series, while fellow Brit Toby Jones is up for Best Actor in a Mini-Series or Motion Picture made for TV, for his role in The Girl.
The Christmas episode of Downton Abbey will be a two-hour show where the family head to a Scottish estate - filmed at Inveraray Castle - to visit cousins, against a backdrop of deer stalking and shooting in the Highlands.
But many of their staff have remained at Downton, and further dramas unfold in the family's absence, in the episode to be shown at 9pm on Christmas Day.
Executive producer Gareth Neame said: "While the cat's away, the mice will play. What will they get up to while the family is away?"
Downton Abbey is to return to ITV1 in 2013 for a fourth series of the Emmy and Golden Globe award-winning drama.
Filming of eight new episodes for autumn 2013 plus an extended special episode for Christmas 2013 begins at Highclere Castle and Ealing Studios in February next year.
Laura Mackie, Director of Drama at ITV, said: “Last year’s special episode set the nation talking on Boxing Day and 2012's Christmas Day episode is no different. As ever, Downton will take its audience through a whole range of emotions. All of life's experiences will feature in this episode.
“This is one episode you will want to see live with millions of others - and best have the tissues ready.” More on this story at ITV Meridian.
