WATCH: Missy Elliott Surprises Viral "Work It" Fan Mary Halsey on 'Ellen'

Missy Elliott super-fan and viral video star Mary Halsey got the surprise of her life this week when she went on the Ellen DeGeneres show to sing the song that made her go viral... and MISSY ELLIOTT HERSELF decided to show up! They both sat down with Ellen, and Missy even got Mary a gift! Ellen couldn't help herself, and also got Mary a gift (a nice jacket with "Missy's Funky White Sister" written on the back! LOL!)

If you don't remember, Mary went viral earlier this summer with her backyard-BBQ-rendition of Missy's Work It, and instantly became an internet sensation.
