Justin Bieber's computer stolen during US stage show
Justin Bieber says "personal footage" has gone missing from his camera and computer after the items were stolen while he was on stage.
The star was performing a show on his Believe tour at the Tacoma Dome in Washington State in the US.
It's not know exactly what was taken.
The teenager tweeted: "Me and my tour manager Josh had some stuff stolen. I had a lot of personal footage on that computer and camera and that is what bothers me the most. #lame #norespect."
The 18-year-old Canadian added in other tweets that "it sucks" and "people should respect other's property".
A Tacoma police spokesman said officers were not investigating because no police report had been filed.
Last week Justin Bieber apologised to fans after vomiting while on stage in the US.
An online video showed the singer being sick on two occasions and leaving the stage after each incident.
