Singer Justin Bieber is reportedly spending 600 pounds-an-hour for taking help from a therapist.

The 20-year-old is allegedly seeing John Kenyon, to help control his impulsive behaviour following multiple run ins with the law, which left him facing charges of assault and drag racing, earlier this year, reports femalefirst.co.uk.

"Kenyon's treating Justin in person, when possible, then over Skype when he's away. Sometimes they even have more than one session a day," said a source.

"Kenyon's so booked up he doesn't normally take on new clients but Justin used his name to skip the three-year waiting list.

"It's too soon to tell if it's having a positive effect, but the fact that Justin has kept it up and passed the first batch of sessions speaks volumes. If he hates something he's not normally the kind of person to stick it out," added the source.

It is said that Bieber was encouraged to participate in the sessions by his mother Pattie Mallette, who has become increasingly worried that his erratic behaviour will be damaging to his career.
