Ed Sheeran's surprise cameo in the Game of Thrones season 7 premiere didn't end with his death. But due to fans sending criticism his way, the singer opted to delete his Twitter account Monday evening. The Brit has said he's not the biggest fan of Twitter in the past. "I go on it and there's nothing but people saying mean things," Sheeran said. "Twitter's a platform for that." Sheeran, 26, has recently come back to Twitter as of Tuesday afternoon.
