Why Joanne Froggatt was mortified after meeting the Duchess of Cambridge

Downton Abbey's Joanne Froggatt will never forget the moment she met the Duchess of Cambridge, especially when it ended with the actress asking herself, "Oh god, what have I just said?" The 35-year-old actress reflected on her royal encounter during an appearance on Conan. Speaking with the late night host, the Golden Globe-winning actress revealed some blush-worthy comments she made to Kate during her 2015 visit to the set of the period drama.

Before even meeting Prince George and Princess Charlotte's mom, the actress and her co-star Michelle Dockery had to film a scene in front of her. "You're just getting more and more nervous," she admitted, adding, "We're doing this scene and she's very beautiful, lovely. She has this amazing aura when she walks in the room."

Calling the experience "nerve-racking," Joanne says she was a bit jittery when the time came to exchange pleasantries with Kate. She went on to recall the meeting, which took place on the set of Lady Mary's bedroom. "She came over to say 'Hi' and I said 'Hello, lovely to meet you' and she said 'It feels strange being in your bedroom,' and I said 'Yeah not very many people get to come in Lady Mary's bedroom' and then I thought 'Oh god, what have I just said?'"

When Joanne noticed what she said, she decided to just leave it alone and act like it never happened. "I thought, 'I'm just gonna be quiet, I'm just gonna be quiet.'" Thankfully, for the British star, Kate just let the joke pass.

Given that Downton Abbey is Kate and Prince William's favourite show, we're sure the mother of two was so happy and overwhelmed to be on the set she didn't even think twice about Joanne's comments.
