The Backpack Kid Celebrates His 17th Birthday With a New EP (and a Final)

Meanwhile, Russell Horning's mom is suing "Fortnite" for allegedly stealing his signature move.

The lead single, "Drip on Boat," features rapper Swaghollywood and showcases Horning’s signature dance move, "The Floss," in a music video recreation of “Napoleon Dynamite.”

“Me personally, I don’t really know the law like that, so I can't tell you if they are taking advantage of me or why,” Horning said. “But my mom and my management team insisted on suing.”

“I always have a final on my birthday,” he joked.
