‘Downton Abbey’s’ Michelle Dockery gushes about Kate Middleton [WATCH VIDEO]

Lady Mary of “Downton Abbey” aka Michelle Dockery gushed about Kate Middleton, the Duchess of Cambridge and said she smelled like roses. “Downton Abbey” is ITV’s hit period drama which will air its Christmas special episode on Dec. 25. After six seasons, the drama is bidding goodbye to the British audience.

Kate Middleton had visited Ealing Studios when she was pregnant with Princess Charlotte in March. The British royal was given the chance to see a scene being filmed in the servants’ quarters for the sixth series of the period drama. She met the cast of the show and chatted with the artists backstage.

Actress Michelle Dockery appeared on “Watch What Happens Live” recently. She was asked by the host of the show Andy Cohen what the duchess smelled like and Dockery promptly replied “like roses,” Hello reports.

Princess Kate was dressed with her baby bump in a cream Jojo Maman Bebe maternity coat, according to Vanity Fair. "Downton Abbey" creator, Julian Fellowes, showed her around, while some of the cast members including Joanne Frogatt, Brendan Coyle and Phyllis Logan, introduced themselves. She met with people behind the production process.

Kate chatted with makeup artists, costume designers, seamstresses, set and prop designers. The mother-of-two also met the show’s youngest actor, Zac Barker, who plays Lady Mary’s four-year-old son George. Dockery was in hand to introduce the two.

Barker, who is one of the twins who play Master George, presented the Duchess with a wooden train for Prince George. Kate then had been very vocal about her feelings for the show, saying that she loved “Downton Abbey,” Huffington Post reports. She even stayed on the sets for an extra half-an-hour.

“Downton Abbey” will leave the small screens this Christmas after six successful seasons. The network released a trailer for the last ever episode. However, fans can also look forward to the Christmas Special Text Santra episode with stars such as Michelle Keegan, Gordon Ramsay, Sir Bruce Forsyth and Gok Wan all making an appearance.

The two-hour special airs on Christmas Day at 8.45 p.m. in the UK on ITV.
