She told Express.co.uk and other press: “Well, somebody kind of leaked photos of us annoyingly, so that’s out, unfortunately.”
Executive producer Melissa Gallant tried to save the surprise for fans and teased: “It’s 1939, it’s the series near the war, which puts all of the characters in an interesting situation.
“Mrs Hall and Siegfried have already been through a war where the other characters are too young to remember.
“So just a really good opportunity to put them under pressure and explore the characters further, in light of the wedding, I can’t say who is getting married…”
