It's official: Lady Mary has insulted Lady Edith for the last time, we just have to wait five months to see it. "Downton Abbey" Season 6 won't air in the U.S. until January, but Michelle Dockery just shared some photos on Instagram to celebrate (and mourn) the end of filming.

"Today is the last day of what has been the most glorious 6 years of my life," Michelle wrote on August 10, in a photo with the twins who play her son. "I am so grateful to have been part of this family. Thank you to each and every one of you out there for watching... @downtonabbey_official #LastDaysOfDownton #finalcountdown."

Here are more memories from Michelle:
