In Downton Abbey, the Countess of Grantham has to compete with one of her maids for the affections of her husband, played by Hugh Bonneville. In real life, she has to hope that the actor is not distracted by the presence on set of Pippa Middleton.

“I became aware of our high-society fans when I was filming a scene and I looked over to Mrs Hughes, the housekeeper, and there was Pippa in my own home of Downton Abbey,” says Elizabeth McGovern, who plays the countess. “I couldn’t have been more thrilled.

“She looked lovely. I had a big chat with her mum, but didn’t get a chance to speak with Pippa herself.”

Mandrake disclosed in October that the Duchess of Cambridge’s sister and parents, Michael and Carole Middleton, had visited the set at Highclere Castle in Berkshire.
