Justin Bieber’s foul mouth landed him in hot water with customs officers when the misbehaving pop star visited Brisbane.

It’s been revealed the 19-year-old was briefly detained at Brisbane airport last month, when customs officers went to check members of his posse for drugs.

He was warned for using inappropriate language after allegedly swearing at a female officer, and also refused to take off his hat and sunnies, the website TMZ is reporting.

Meanwhile, the status of a legal case against a member of Bieber’s entourage remains unclear.

One of his minders had been due to face a Brisbane court on Friday after also getting into hot water with customs officers.

But media reports suggest the case has been settled after the man paid a fine. AAP is seeking clarification.

The pop star’s visit to Queensland was a shocker for the star, whose bad-boy antics have tarnished his once squeaky clean image.

After one of his Brisbane shows, Bieber and his gang posted photos of themselves spraying graffiti on a wall at the ritzy Gold Coast hotel where they were staying.

The vandalism was welcomed by the hotel as “art” that would be a lasting memento of Bieber’s stay. But the local mayor was furious and said the star should return to Queensland and clean up his mess.

Bieber’s concert tickets were once the hottest property in town but his popularity has been on the slide of late.
