Report: Justin Bieber Takes DNA Test, Prepares To Sue Mariah Yeater

Justin Bieber has made good on his promise to take that DNA test -- and prove once and for all that he did not father Mariah Yeater's baby son. According to TMZ, Bieber went to a lab on Friday night in New Jersey, where he took the test under "very controlled circumstances."
