Justin Bieber is reportedly being urged to seek help in rehab.

The 'Heartbreaker' hitmaker has been advised by those closest to him to seek treatment for his alleged use of recreational drugs and behavioural issues following a police raid on his home in Calabasas, California on Tuesday (14.01.14).

An insider told gossip website RadarOnline.com that Justin's friends and family are ''deeply concerned'' but the 19-year-old star has no plans to check into a facility.

Another source said: ''The people who care about Justin and whom are closest to him wish he would consider getting help.''

A source previously claimed that Justin's on/off girlfriend Selena Gomez, 21, had asked him to attend anger management classes following a string of bad behaviour, which includes allegedly throwing eggs at his neighbour's home last week, a prank that resulted in his home being raided.

A source recently said: ''Selena is an old fashioned southern girl from Texas and believes in manners and good behaviour, she's told Justin that he has to mend his ways if they are to start seeing each other regularly again.

''Selena has been on her own and what she calls 'on the road', but she hasn't stopped being attracted to Justin. She just wants some pleases [and] thank yous, as well as some good behaviour if things are to get serious again.

''She has told Justin he needs help with anger management and that he should book classes.''
