The 'Last Request" hitmaker prefers focusing on making music than telling fans about his day-to-day life. He said: "I don't think: Oooh I am going to tell everyone I know that I just woke up. I don't care if the fans know that because I'd rather they know I'm concentrating on my music. Plus I don't have the time."
Ashton Kutcher, Demi Moore, Lily Allen and Katy Perry are some of the stars who regularly use Twitter.
