Selena Gomez -- My Rear Got Banged Up

Selena Gomez's rear was slightly damaged Sunday in North Hollywood … in a fender bender she allegedly caused.

Gomez was pulling out of a 7/11 parking lot when she backed into another vehicle -- causing some minor damage to her SUV. Immediately afterward, she tweeted and seemed to be blaming paparazzi for distracting her.

Unclear what if any damage was done to the other car, but Selena exchanged info with the driver -- and, so far, cops haven't been called … so it looks like she's in the clear.
