Aussie rapper Iggy Azalea has announced her split from basketballer Nick Young.

The 26-year-old star announced the split on her Instagram page.

"Unfortunately, although I love Nick and I have tried and tried to rebuild my trust in him - It's become apparent in the last few weeks I am unable to," she wrote.

"I genuinely wish Nick the best. It's never easy to part ways with the person you planned you're entire future with, but futures can be rewritten and as of today mine is a blank page.

Azalea - who is set to replace Dannii Minogue on the judging panel in the upcoming season of The X Factor - had been dating the Los Angeles Laker star since November 2013.

The couple had announced their engagement in June 2015.

Back in March, a video surfaced online which appeared to show the 30-year-old basketball player confessing to cheating on his famous fiancee.

The video was filmed months before that by one of Young's basketball teammates, D'Angelo Russell, but it's not known who leaked it online.

Azalea responded on Twitter, saying: "If there's proof of cheating, she'd be doing me a favour to post it actually. Im not tryna marry a cheater."

The rapper told TV host Ryan Seacrest around that time that the wedding would be delayed.

"It was going to happen at the end of the year, but now I have to go to work so we'll probably have to wait until the end of the next basketball season to do that," Azalea said.

"So that kind of is a bit sucky, but it's all right."
