After returning from the South American leg of his Believe Tour, Justin Bieber's private jet was searched by customs officials at Los Angeles International airport on Wednesday morning. No word on whether agents found anything, but it appeared to be a routine search and Bieber walked calmly to his car on the tarmac.

This isn't the first time Bieber's been searched -- back in April his tour bus was raided by Swedish police, and authorities found a "small amount" of what appeared to be marijuana.

Bieber performed in Chile on Tuesday night, and though that show went according to plan, on Sunday evening Bieber canceled his concert at the River Plate Stadium in Buenos Aires, Argentina due to food poisoning. The 19-year-old pop star took the stage an hour and a half late, but after about an hour of singing he called it quits. "I’m not feeling too good, I think I’m out of energy," he told the audience, before blowing them a kiss and walking off the stage. Bieber also walked off the stage in Brazil last week after someone threw a plastic bottle at him.

As far as drama off the stage, the pop star was photographed leaving a brothel with two young ladies the previous week, and he was then allegedly kicked out of his hotel room in Rio for "partying, doing drugs and disturbing people," at which point he rented a mansion and had a party with a handful of girls he had met at a local club.

Bieber's next stop will be at Mexico City's Foro Sol stadium on November 18th. Hopefully he stays out of trouble while he's in LA!
