He's the creator of the show, so if anyone knows when Downton Abbey will end it's Julian Fellowes.
But the 65-year-old screenwriter has insisted that how and when the period drama will finish isn't ultimately down to him.
Explaining that he doesn't 'own' Downton, Julian has told The New York Times that any decisions regarding the finale of the hit series will be made by the show's owners, NBC Universal.
Amid mounting rumours that the ITV production will end after the sixth series, which will air in the UK later this year, Julian told the newspaper: 'It's not really my decision. I don't own Downton Abbey now.
'NBC Universal [which owns Carnival Films] owns Downton Abbey. So I could walk away. But I wouldn't walk away. It's too much my baby.'
The writer added that he 'can't immediately' say exactly when the show will end, but went on to admit that he wouldn't want to continue the storylines of the Crawley family past World War Two.
'Maybe people would say, "Oh my God, that's baby George, grown up!" But I don't think it would be continuous, with Michelle Dockery with her hair covered with talcum powder.'
Rumours that Downton will come to an end this year first started circulating In January, but ITV were quick to shoot down the reports as 'speculative'.
Julian though is moving to New York to work on a new period drama, meaning the rumours of his British-set period drama's imminent end are looking more and more likely.
The show's star Dame Maggie Smith, who plays Violet Crawley, also appeared to signal the end was nigh as she said she was ready to leave the show last week.
The 80-year-old has since clarified her remarks with a representative telling The Wrap: 'Maggie has always been on the record as saying she'll be with the show for as long as the show runs.'
This comes after Smith, said that she she can't see how programme can continue after the upcoming sixth season.
'They say this is the last one, and I can't see how it could go on,' the legendary actress told the Sunday Times.
Continuing she quipped: 'I mean, I certainly can't keep going. To my knowledge, I must be 110 by now. We're into the late 1920s.'
