Call the Midwife has welcomed Charlotte Ritchie to the series as Nurse Barbara Gilbert, and as happy as the actress is to be on the show, it's not all rainbows and butterflies.

'Call The Midwife' Actress Dishes On Her Character's 'Horrible Story'

On Thursday, Radio Times posted an interview with Ritchie who said that she was once a huge fan of the show. But now that she's a part of it, it's not quite the same anymore.

"I have been watching the episodes as they go out," she said. "It's horrible! I've ruined the show for myself."

Ritchie also said that she used to let her tears out in all the episodes before, but this time she hasn't cried at all.

"I haven't cried yet in this series, but I think it's because I'm in it," she said. "I've really broken the magic for myself. It's such a shame!"

Even though her emotions may have changed, the actress is definitely still a fan.

"It's still a gorgeous show. I still enjoy it," she said. "Maybe just like 75% now."

Ritchie also spoke a little on her character and how Nurse Barbara might be someone who takes a little time to get used to.

"She's a new character and it's such an established show, you might be a bit protective over it," the actress said on her character. "I know I am. I'm annoyed that I'm in it!"

Call the Midwife Season 4 is expected to air in the United States this spring on PBS.
