Justin Bieber was reportedly detained for five hours by US Customs after landing at Los Angeles' LAX airport.
The pop heartthrob flew into America after an international trip, with different sources saying he was arriving from either Tokyo or Singapore, and was reportedly taken aside for questioning by US Customs and Border Protection.
Justin, 20, was with his bodyguards, who were said to be waiting outside for him while he was quizzed.
It's unclear why the Canadian star was questioned.
A source told MailOnline: "Justin was held up upon arrival while his bodyguards and his luggage were waiting outside for him. He went through routine secondary questioning but has now been released."
The Baby singer was later photographed leaving the airport, flanked by his security team.
