Iggy Azalea Shows Mo Bounce Rehearsing 'Kream' Moves for Concert

Iggy Azalea isn't just serving up her own ample ass ... this time, she's got a whole gang o' asses with her -- strictly for biz, of course.

Yes, here's Iggy's day at the office, rehearsing some moves for her song, "Kream" ... we're assuming for live performances. ZERO pretense here -- just a whole bunch of butts shaking, popping and clapping.

If you've seen the "Kream" music vid, the dance moves here aren't exactly a surprise, but they'll likely inspire you to grab some Iggy concert tix!

The only downside here is for Iggy's dancers. It's not like they can tell friends and family to check out their latest work. The camera angle reveals NO faces.

Still, impressive work ... even if ya can't ID 'em.
