Bieber willing to take paternity test

Justin Bieber is willing to take a paternity test to prove he is not the father of a fan's baby.

The 'Mistletoe' singer has been left stunned by Mariah Yeater's lawsuit in which she has accused him of being the dad of her four-month-old son and he insists he is ready to take a DNA test to prove he isn't the tot's parent.
