Iggy Azalea's Ringing Endorsement for Sticking with Nick Young

Iggy Azalea is not breaking off her engagement to Nick Young ... not yet, anyway and she wanted everyone to know it at the iHeartRadio Awards.

Iggy posed for photogs Sunday night in L.A. with her right hand in her pocket, but made sure her left -- weighted down with that massive yellow diamond ring Nick gave her -- was fully exposed.

As TMZ Sports first reported ... Nick's been desperately trying to save the engagement since the D'Angelo Russell video leaked.
