Justin Bieber got a nasty surprise this Tuesday - he got robbed during one of his concerts.

Justin tweeted about what happened:

"Yesterday during the show me and my tour manager Josh had some stuff stolen. Really sucks. People should respect other's property."

Justin wasn't just upset about getting his stuff stolen, but more about having the personal stuff gone:

"I had a lot of personal footage on that computer and camera and that is what bothers me the most. #lame #norespect."

And Justin's bad night didn't end there. Later, somebody called the police saying they'd seen somebody with a gun outside Justin's house. The police rushed over with squad cars and even a helicopter…and found out it was a joke.

Poor Justin, Tuesday really wasn't his day! Hopefully he'll get his stuff back.
