Ed Sheeran is gearing up for his North American tour [1], and on Friday, the English singer [2] performed his new track "What Do I Know?" during the Comic Relief charity event [3] on Red Nose Day. The song is off his new album, Divide [4], and Ed must have been a little nervous because he stumbled over a couple of words around the 0:24 mark. However, being the pro that he is, Ed managed to laugh the whole thing off and carried on.
