A self-admitted big fan of hit TV series "Downton Abbey", Kate Middleton stopped by its set at Ealing Studios in West London at 10:15 A.M. local time on Thursday, March 12. The pregnant Duchess was all smiles as she met everyone on the set, ranging from writer and show creator Lord Julian Fellowes, executive producer Liz Trubridge, makeup artists at work, costume designers, seamstresses and cutters in the workshop, to the people behind the design and production process of set scenery and props.

In addition to those people, Kate made time to greet a bunch of the series' stars, including Phyllis Logan, Robert James-Collier, Lesley Nicol, and Sophie McShera. She was later on presented with a posy and wooden train by the cast's youngest member Oliver Barker, who plays Lady Mary's son, Master George Crawley, who met her alongside his on-screen mom Michelle Dockery.

Even greater, the Duchess had the chance to watch one take of a scene being filmed in the servants' quarters (a bedroom) for season six, and a second take of the scene via a monitor in the "Video Village" area. Later on during her hour and a half visit, Kate also made time to pose for some photos with cast, crew and producers of "Downton Abbey" and an official photograph at the Servants' Hall.
