Michelle Dockery has secret Instagram account for her dog

Michelle Dockery has a secret Instagram account dedicated to her pet dog.

During an appearance on The Tonight Show Starring Jimmy Fallon on Monday night, host Jimmy asked the Downton Abbey actress why she isn't on social media.

Michelle went on to reveal that she does have Instagram, but only posts photos of her dog.

"I have one for my dog. I'm one of those," she laughed. "And then I stalk everyone."

The star insisted that no one knows about her account and she really only uses it to get interior design inspiration.

"I post photos of my dog and then I follow lots of interior designers," the 40-year-old smiled. "I just love interiors. I like looking at nice houses... It's quite boring, really."
