Bieber is two years below the legal drinking age in Dubai, which means he won't be allowed to drink in most nightclubs around. But one of the clubs has shipped in a specially-made 24-carat gold ping pong table to keep him occupied.
The singer is not even allowed to bring his girlfriend back to his hotel. Bieber's team have asked Selena Gomez to stay in a separate hotel if she visits because of the strict laws over unmarried couples sharing a room.
"Everything is on lockdown because Justin's management know he'll be watched like a hawk by the authorities. His team have been scouting the area for things for him to do instead of going to bars all night," a source said. "He can't even stay in some of the best restaurants after midnight and has to be with an adult until then," the source added.
