Selena Gomez Tryin' to Stay Outta the Gutter

7/24/2013 4:30 AM PDT
Selena Gomez just turned 21 ... and she’s already stumbling in NYC. 

Don't worry ... this fall doesn't appear to be alcohol-related -- just seems like Selena lost her footing on the way out of her car.

Luckily, a bodyguard was there doing the job he was hired to do -- protect her body -- and kept her from face-planting in the gutter.

Happy belated!
