Justin Bieber is reportedly taking ‘sizzurp’ with “alarming regularity”.

The 19-year-old singer has been in trouble with the law several times, including allegations of speeding in his car and assaulting a neighbour.

Now TMZ is writing that Justin is being urged to head to rehab by his people after being associated with the drug mix, which was thought to have been linked to Lil Wayne’s hospitalisation last year.

“Multiple credible, connected sources tell us... Bieber has been using sizzurp regularly. It's typically codeine and promethazine mixed with Sprite and a Jolly Rancher. Bieber and his crew refer to it as ‘lean.’It's a very dangerous narcotic that can trigger seizures, and even worse,” the website writes.

TMZ also claims Justin is using marijuana and prescription pills including Xanax, as well as drinking alcohol.

However, their sources say he has never been involved with cocaine.

“We're told a number of people are very worried and have urged him to get help - including going to rehab,” the website finishes.

Justin hit headlines again recently when he was accused of pelting his neighbour’s home with eggs.

Subsequently his Calabasas, California, house was raided by police to check for evidence that the star had caused $20,000 of damage to the property.

Rumours have been circulating that those close to him would feel relieved if Justin chose to complete a stint in rehab.
“People around Justin want the best for him and hope that at some point he'll recognise the need for some help,” and insider told the MailOnline.
