Justin Bieber's private jet was stopped and searched for marijuana as it landed in the US today (31.01.14).

The 'Confident' singer has travelled from his native Canada to New Jersey for this weekend's Super Bowl with his father, Jeremy, and friends, but they ran into trouble when authorities thought they could smell the illegal drug on the aircraft.

According to TMZ.com, the plane and the passengers were held at Teterboro airport while the craft and persons onboard were searched, but nothing was found and all passengers were then let go.

The website adds a source close to Justin's camp said they knew they would be subject to security checks, as they had flown over an international border, so were unlikely to be carrying anything illegal.

Justin,19, currently faces legal troubles in Los Angeles, Toronto and Miami, with the latter being where he was arrested and charged with driving under the influence, resisting arrest and driving without a licence on January 23. Under questioning by cops, he admitted to having smoked marijuana and taken prescription medication given to him by his mother, Pattie Mallette.

Justin's former girlfriend, Milyn Jensen, has previously claimed his cannabis habit is out of control.

She said: ''It's no secret that Justin loves his weed - there's probably not a moment in the day when's he's not got a buzz on.

''He's surrounded himself with the wrong people. He didn't want to be the cheesy popstar anymore and has gone way too far the other way.''
