Pastor: 'Justin Bieber is turning his life around'

Justin Bieber's pastor is adamant the troubled pop star is making good progress as he attempts to turn his life around amid news he is a wanted man in Argentina.

The Baby singer, who has endured a slew of legal problems over the past year, is wanted for questioning in Argentina in connection with an alleged attack on a local photographer in Buenos Aires last year (13) and he has 60 days to turn himself over to authorities.

His pastor, Carl Lentz, has spoken out amid the latest headline-grabbing furore to insist the 20 year old is making good progress with his spiritual guidance.

Lentz tells the New York Post, "I remember (when I first met him) just looking at him and going, 'This is going to be a challenge'... And that day being like, 'I'm going to pray for this boy to make it'... I have a special role in Justin's life, spiritually, but... I'm not a life-motivational guy... We're talking about making sure his life remains a blessing, not a burden... He's on a journey. If he's not doing good, should we abandon him?"
