Justin Bieber writes song about paternity claim

Justin Bieber has written a song about the California woman who sensationally accused the singer of fathering her child last year.

The Baby hitmaker hit headlines in November when Mariah Yeater, then 20, falsely claimed Bieber had impregnated her during a backstage romp at one of his concerts in Los Angeles in 2010.

The singer vehemently denied the claims and even voluntarily took a DNA test to put an end to the scandal, and he has now documented the experience in a new track for his eagerly awaited album Believe.

He tells Heat, "I'm going to be talking about everything I'm going through. I've written a song about that whole situation with that girl who said she's having my baby - Mariah Yeater.

"I've written about my mum, loads of things I'm going through."
