Justin also dyed his hair platinum late last year. He is just one of many to rock the look this year, including Jared Leto and Kim Kardashian.
During his appearance, Justin was honored with a Guinness World Record plaque for being the youngest male artist to have a song debut at #1 on the Billboard Hot 100, with his latest single, “What Do You Mean?”
