Basketball star Nick was caught out last month (Mar16) after confessing to being unfaithful to the Fancy rapper in a leaked video recorded by his Los Angeles Lakers teammate D'Angelo Russell.

The Australian star brushed off the drama and insisted she and her beau are still on good terms, but in an interview on U.S. radio show Orlando and The Freakshow, she said another similar incident will result in her fiance losing part of his manhood.

"I'm not cool with it (cheating)," Iggy said. "Like, you'll have half a penis. I already said one more video, just one more thing and you will lose a quarter of your meat."

After it was pointed out that it was not known if Nick had actually cheated on her, she added, "Well, that's why he (Nick) got to slide this time."

Speaking about her engagement, she said, "I have an actual spoken commitment that you're going to get married to me and that involves not doing any of those other things."

Despite the controversy and her brutal warning, Iggy, 25, told fans on Twitter last week (beg04Apr16), she had forgiven Nick and they had no plans to split, writing, "When youre (sic) grown and actually build a life with someone you might understand... yeah, thats life... youll f**k up in your own ways too, relationships are hard work (sic)."

Nick, 30, popped the question last year (15) and the couple was planning to marry later this year (16), but the wedding has been delayed so Iggy can embark on a tour.
