The character of Lily James' free spirited and fun loving Lady Rose Aldridge has been missing in "Downton Abbey" season 6 especially since she got married, but for the show's last episode, she and her husband Atticus Aldridge will be back - and possibly with big news too.

Earlier, James said that she would jump at the chance to reprise her role in "Downton Abbey" if only creator Julian Fellowes asked her to be back. The 26-year-old actress got her wish in the end, because her character will be making her reappearance in the Christmas special.

"It was amazing going back after a break. You are just totally re-inspired by the wonder of it, that grand house against grey skies and all the friends you haven't seen in so long," the actress told Harper's Bazaar about reprising her role as Lady Rose.

"I have such happy, positive memories and a sense of accomplishment about being on the show. I don't know if I'd be sitting here if it weren't for Downton. It would have all been very different," she added.

The only news fans had about her character during the sixth season was in a letter ready by Lady Mary, who said that Rose is "hectic and happy" and that "New York is heaven."

Lady Mary even thought that Rose could be pregnant, especially since Rose wrote, "I might be back in August, but it's a bit early to say."

However, Mary's sister Edith thought she was jumping to the wrong conclusion since she commented, "As usual, you add two and two and make 53."

James had been very busy especially after she starred in Disney's live action movie "Cinderella" together with "Game of Thrones" star Richard Madden. She will next be seen as Elizabeth Bennett in the spinoff film "Pride and Prejudice and Zombie" together with her beau Matt Smith, who will portray her character's failed suitor Mr. Collins.

She will also be appearing in the BBC adaptation of "War and Peace," although she said that it will probably be the last period piece she will be doing for a long time since she wanted to "steer away from period stuff."

James was actually reading Leo Tolstoy's novel while filming the Christmas special of "Downton Abbey."

"The sound guys used to laugh at me because we'd be sat round the dining-room table and just before they'd say, 'Rolling!' there would be a huge boom as I dropped this brick of a novel under my chair," she shared.
