Justin Bieber Hey NYPD Dinner's On Me!

(TMZ)Justin Bieber came face-to-face with a group of NYPD officers Friday night ...
and even though they took a picture of his mug -- it was only out of
appreciation for his generous donation. Bieber was eating at the Comfort Diner
in NYC when he noticed a few officers eating next to him ... so when it came
time to pay up, Justin coughed up the dough for their tab -- around $200. The
officers walked over and thanked Bieber for hooking them up ... then snapped a
pic -- which Justin posted on Shots -- so they could prove to their family the
whole thing actually went down.
