'Downton Abbey' cast pokes fun at water bottle goof for charity

"Downton Abbey" made waves last week when a promotional photo of Lord Grantham and Lady Edith for the upcoming season included something that was a bit out of place — a very modern water bottle in the background.

But the cast turned the goof, dubbed "Water Bottle Gate," into something positive: support for WaterAid, a group that works to provide access to safe, clean water to poor communities around the world.

The show tweeted out a photo on Saturday, showing the cast in their very modern duds, goofy faces and each holding a plastic water bottle. 



"The cast and crew came up with the idea of turning some of this attention towards an issue around water that really matters," a spokesperson for ITV, the network that airs the show in the UK, said in a press release on the WaterAid website. "They hope that by posing for this picture, they will be able to raise awareness and amplify the work of international charity WaterAid."

According to WaterAid UK, donations will be doubled until Sept. 9.



The stars of the period drama have also been urging fans to donate.





The cast and crew recently finished filming the upcoming season, and star Joanne Froggatt, who plays Lady's Maid Anna, shared a silly photo to mark the day.



Season five premieres in the United States on Jan. 4 on PBS.
