Singer Justin Bieber says he is a very independent person and that his mother and mentor, Singer Usher, keep him grounded

London: Singer Justin Bieber says he is a very independent person.

"I guess I`m fine with being by myself. I`m a very independent person, so I don`t really get lonely. I don`t get much time to myself," he said. "I work a lot, but at night time, that`s basically my down time when I get to just lay in bed, play on my computer, check twitter and all that. I never get to feel anonymous anymore, not really." The 16-year-old teen sensation admits that he relies on his mother, Pattie Mallette, and music mentor Usher to keep him "grounded", reports a website. "I have some great people on my team that keep me grounded, my mum is always with me and they keep me sane, and Usher has been there, so he knows, he helps keep me sane," he said. IANS
