Knock, knock. Who's there? It's OPRAH.

Except we're not joking. If you live in Georgia and hear a knock at your door today, there's actually a chance that it is indeed actress, activist, television host, author, etc., Oprah Winfrey.

How is this possible? Well, with less than a week left until the midterm elections, Oprah's going door to door to canvas for Democrat Stacey Abrams who's running for governor of Georgia.

After speaking at a campaign for Abrams early on Thursday, Oprah started knocking on the doors of Georgia residents' homes to ensure that they have plans to vote on Nov. 6.

"U never know who’s gonna come a knocking!" Oprah wrote on Instagram alongside a video of her knocking on the door of a woman named Denise.

Once Denise got over the shock of Oprah showing up on her doorstep, the former talk-show host got down to business and asked if she was supporting Abrams, and if she had an early voting plan.

Oprah also posted another video of a woman named Cassie holding a sign about equal rights that caught her attention while canvassing.

Though it's hard to imagine the excitement of Oprah coming to your house to talk about politics, this isn't the people of Georgia's first brush with celebrity voting campaigns.

Earlier this week actor Will Ferrell knocked on doors to support Abrams.

And on Friday, President Barack Obama will make his way to Georgia to support the gubernatorial candidate and host a "Get Out the Vote" rally at Morehouse College's Forbes Arena in Atlanta.
