"If you perfect then be perfect I live in a world where ppl f--- up learn from it and move on ..." he wrote Friday evening. "That's life ... hate me or love me I'm still going to love life man."
On Thursday morning, the rapper sent a series of tweets explaining why she called off her engagement.
"I broke up with Nick because I found out he had brought other women into our home while I was away and caught them on the security footage," she wrote.
News of the split was accompanied by tabloid rumours that Young had cheated on Azalea with his former girlfriend – and mother of his 4-year-old son Nick Jr. – who is now allegedly pregnant with their second child.
"I have never even been told by nick that his baby mother is pregnant so if this is true I'm finding out via E news," Azalea tweeted. "This is just like a second shot to the chest. And I feel like I don't even know who the hell it is I've been loving all this time."
Until Friday, Young's only comment on the breakup was a tweet simply reading, "Single," sent shortly after Azalea announced their split on Instagram on June 19.
The couple, who got engaged in June 2015, stuck together through allegations of Young's cheating earlier this year. Shortly after a video allegedly showing Young bragging about cheating on Azalea was leaked by one of his Los Angeles Lakers teammates, the Australian musician brushed the drama aside, citing the clip's questionable legitimacy, but threatened to cut off Young's manhood if the rumours turned out to be true.
"That's why he got to slide this time. I was like, 'Just let me get some real evidence, and you're gonna lose half an inch,' " she joked in an interview with radio station Wild 94.1.
