Bieber writes song about woman who claimed he fathered baby

Justin Bieber has written a song for his new album about the woman who accused him of fathering her baby.

The 18-year-old singer has penned a track for his forthcoming record 'Believe' expressing his feelings about Mariah Yeater, a fan who claimed last year that he was the dad of her son, Tristyn, before she dropped a paternity case against him and confessed her ex-boyfriend was the child's real dad.
