'Trust issues' to blame.
After this March's cheating scandal (in which Nicky Young appears on video confessing to stepping out on his fiance Iggy Azalea) it should come as no surprise that the pair are now officially calling it quits.
In an Instagram post, Iggy announced that "as of today, [my future] is a blank page", and saying that although she loves the basketball player, and she's tried to rebuild her trust in him, "it's become apparent in the last few weeks I am unable to".
Her ex made a similar announcement on Twitter, albeit a lot more succintly.
"Single", he tweeted.
