Controversial singer Justin Bieber and his entourage allegedly filled their Super Bowl-bound plane with so much marijuana smoke that pilots were forced to wear masks, according to a police report obtained by NBC News.

Despite the pressurized cabin, the pilots have to wear the masks, according to NBC's multiple sources, so they wouldn't risk inhaling the substance. Inhaling the smoke could jeopardize their career and will out their license at risk.

Bieber and his father are reportedly "abusive" to a flight attendant as their private jet flew from Canada to New Jersey that she was forced to sit in the cockpit. The Canadian pop star's entourage includes 10 of his friends aboard the luxurious Gulfstream IV.

The official report reads: ""The captain of the flight stated that he warned the passengers, including Bieber, on several occasions to stop smoking marijuana. The captain also stated he needed to request that the passengers stop their harassing behavior toward the flight attendant and after several warnings asked the flight attendant to stay with him near the cockpit to avoid any further abuse."

The private jet was met by DEA and Customs and Border Protection agents and the police the moment they landed at Teterboro, a small New Jersey airport. When federal authorities checked the reported place, the cabin still smelled like marijuana according to NBC.

When he was interviewed by authorities, the 19-year-old star admitted of smoking marijuana and drinking alcohol while on the flight, but no unsmoked weed was found during the search. The authorities even brought a drug-sniffing dog to alert them for possible presence of drugs but to no avail.

Members of the flight crew did not file any charges against the singer so they were allowed to go on their way to the Super Bowl. After Bieber's entourage left the scene, authorities found empty bags that appeared to have once contained cannabis but they can't link it to Bieber's crew, or his father.

This incident is Justin's third encounter with law enforcement in recent weeks. He was arrested by authorities late January due an alleged drunk driving after an alleged drag race.
