Pattie, who gave birth to Justin when she was 17-years-old, asked people not to judge her son but to pray for him.
She told The Sun: ‘I ask that people keep me and Justin in their minds. I pray for him every day.’
She added: ‘If Justin's struggling, don't kick him when he's down or condemn him - pray for him.’
Justin has been making the headlines regularly for the past few months due to his outrageous behaviour.
The 19-year-old singer is reportedly in hot water following an egging incident, which led to £20, 000 worth of damage to his neighbour’s property.
More recently, the pop star reportedly spent thousands of dollars at a strip club in Miami after a weekend skiing in Colarado.
He then shared an Instagram pic of himself smoking a Cuban cigar.
Pattie defended Justin, saying: ‘I think so many people go into the entertainment industry with amazing Christian roots and they get influenced somehow.’
37-year-old Pattie wrote a book about her own struggle with drugs and her attempted suicide as well as her life as a teen mother.
