Iggy Azalea -- Cop Cuts Her Ass a Break

Iggy Azalea got busted for banging an unsafe left turn in Bev Hills, yet managed to wiggle her way out of the ticket ... and didn't even have to play the "don't you know who I am" card.

Law enforcement sources tell TMZ ... Iggy got pulled over Monday afternoon for unsafe driving -- but guess it was her lucky day.

We're told the officer let her off with a warning ... mostly because she was cool and understood she'd screwed up. Best of all, he never knew she was a famous pop rapper.
