Hope he knows as much about diapers as he does about crooning. Self-made teen idol Justin Bieber, 16, plans to take a break from his busy promotional schedule after recently learning that he got a young fan pregnant late last year. Classy guy he is, he plans to take care of her, and has already asked for her hand in marriage. He plans to hold a press conference later today, which TMZ plans to stream live. All of this came at an awkward time for the superstar, whose album “My World 2.0” just hit the top of the charts and whose throng of teen fans may not approve. source
