Justin Bieber Baby Mother Gives TV Interview

The new mum who claims baby-faced Justin Bieber is the dad of her baby has spoken out in a TV interview.

Mariah Yeater, 20, is claiming Justin, 17, slept with her back-stage after one of his concerts, and is the father of her four-month-old baby, Tristyn Anthony.

The singer is denying Mariah's claims, and is rumoured to be taking a paternity test to prove Tristyn is not his baby, baby, baby (sorry!).

Watch the interview for Mariah's side of the story. Needless to say Justin's army of loyal teenage fans aren't too happy with her...
