Oh my gosh, if you remember correctly, earlier this summer Mary (an amazing karaoke master) performed Missy Elliot's "Work It" at some sort of bbq party and absolutely slayed it like a boss.
Now that you're refreshed, Ellen found out about this video and Mary got to come on Ellen and perform. Of course, it wouldn't be Ellen if she didn't bring Missy Elliott out and she totally did. It is the best thing I've seen all day! Check it out below and click here to watch Mary and Missy sit down and chat with Ellen.
