Iggy Azalea may still be engaged to fiance Nick Young -- but she's certainly not letting him off the hook easily!

Last month a taped conversation emerged of Young admitting to cheating during a conversation with his Los Angeles Lakers teammate, D’Angelo Russell, and sh*t really hit the fan. Amazingly enough Iggy is staying with him, but over the weekend the rapper appeared on the "Orlando & The Freakshow" radio show on Wild 94.1 and said that if anything else happens -- she's gonna cut off his penis. Yep. That's what she said!

When the radio hosts brought up the cheating scandal, Iggy quickly said she was not at all happy with what had gone down and wasn't about it let it happen again. The 25-year-old said, "I’m not cool with it. Like, you will have half a penis. I already said, I was like, ‘One more video, just one more thing, and you will lose a quarter of your meat."

Well it looks like if Nick messes around again he's gonna get the axe -- in one or another!

Iggy keeps saying she's staying with her cheating man -- but if she has to threaten to go Lorena Bobbitt on him -- maybe she should rethink her relationship status?!
