In 2013, Justin Bieber performed in Dubai for his Believe Tour on May 4 and 5. The second show was added later, due to an overwhelming demand and rapid sell-out. He arrived approximately two hours late to both of the shows. The singer, who was 19 years old at the time, took to the stage at roughly 10pm on the first night. He did it again, despite criticisms, on the second night. Many parents who had accompanied their young fans to the concert slammed him for being disrespectful and inconsiderate. But his tardiness was expected by many, since he was well-known for showing up late to a number of his concerts.
