Word to the paps: don't mess with Justin Bieber.
On a recent shopping trip in the 305, the Biebs threw a water bottle at the paparazzi when they were chasing the pop singer in the street.
The "As Long As You Love Me" crooner looked mad at being followed and was photoed launching the empty bottle into the crowd.
This is not the first time he's had an altercation with photogs. In May, the singer confronted a paparazzo when he tried to take pictures of him and his on-again, off-again girlfriend, Selena Gomez.
In other Biebs news, according to TMZ.com, a New Mexico man, who is currently in prison and serving two life sentences for raping and killing a 15-year-old girl in Vermont, recruited a fellow inmate to have JB murdered and castrated.
