Justin Bieber wants to put the rumours that he fathered a child away completely. He has agreed to take a paternity test.

Last week 20-year old Mariah Yeater claimed she had given birth to Bieber’s son 3-months ago. She claimed she had sex with Bieber backstage after one of his concerts 12 months ago.

Bieber has denied ever meeting the woman. Also, her ex-boyfriend came forward to say that she tried to pin the child on him as well.

Justin Bieber will take the paternity test and then use the results to sue the woman, his rep said.

Bieber is in London this week. Yesterday, he switched on the Christmas lights at Westfield in London.
