A video of a South Carolina girl singing at a McDonald's has gone viral in a big way. 16 year old Cecily Hennigan belted out the "McDonald's Drive- Thru Song" at a local McDonald's. One of Cecily's friends took a video of Cecily singing and since last week, the video has been viewed over 14,000 times! Cecily is hoping that the video will go big, so she can make an appearance on "Ellen."
Here's Cecily belting out her order! Super size it baby!
