Late last week, bottle-gate hit the intertubes, and no one could believe it. On Sunday, the cast took to Instagram to post their regrets, with each member of the cast cheekily cheers-ing with a water bottle of their very own. What's really great about it, however, is the fact that they took the apology as an opportunity to spread the word about charity WaterAid. Nicely done, Downton. Cheers to that.
