The brat pictured leaving his Stockholm hotel!

For most of this year, Justin Bieber has been dogged by controversy.

Now you can add drugs and a stun gun to the list of Bieber bombshells.

Swedish police say they have found drugs on board a tour bus used by the Canadian pop singer.

The raid was prompted after one of the officers working the crowd outside the Globen concert  venue in Stockholm smelled a suspicious odor coming from the bus.

Police spokesman Lars Bystrom told the AP that in addition to the substance – which local Swedish paper Aftonbladet reports is marijuana – a stun gun was found when officers boarded the bus parked under the concert venue, where Bieber was performing Wednesday. Bystrom also said that the substance had been sent to a laboratory for an analysis.

The pop star, 19, had entered the arena about a half-hour before the raid, according to reports.

The spokesman said several people were on the bus at the time of the raid, but police did not have a specific suspect, and no criminal charges were pending.

Bieber’s brat-like antics during his world tour have seen him making headlines almost every other day.

Over the weekend, during a paid photo shoot for cosmetics giant Elizabeth Arden in Copenhagen, Denmark, he reportedly threw a temper tantrum after he was asked to wear a bell boy hat. Oh, and he turned up six hours late for the shoot.

A source told RadarOnline.com: ”After showing up six hours late, Justin threw a temper tantrum because they wanted him to wear a bell boy hat — but he refused.

“This kid is quickly getting a reputation as someone that no one wants to work with. It was disgraceful.”

He also refused to leave a tip after dining at a high-end restaurant on Friday night with Selena Gomez. The meal was said to be complimentary and Bieber believed that so too, was the staff’s hard work.

“It was very low class and just disrespectful. Selena acted like a true lady, but Justin acted like an entitled punk,” a source told RadarOnline.

Bieber arrived Thursday in Finland and wrote cryptically on Twitter: “some of the rumors about me….where do people even get this stuff. whatever…back to the music.”
