Iggy Azalea filmed herself burning her ex-fiancé Nick Young's designer clothes.

The Fancy hitmaker has confessed to setting alight to the various items after she allegedly caught the basketball player having sex with another woman in 2016.

During an appearance on Watch What Happens Live With Andy Cohen, she revealed: "I burned it all, darling! I burned a lot, and I threw stuff into the pool too. I started off with water and it just seemed like that didn't work.

"Every designer you can think of, I burned. See this is what I did.

"He was out, and I used to break stuff in our house and I realised I was breaking my own s**t, like that's stupid, and he didn't care.

"So I was like, I'm going to find something you care about and I'm going to start destroying that, which was his clothes, and we had a fire pit outside, a nice fire pit you can put on with the gas."

However, instead of leaving him to come home to find his wardrobe burnt to pieces, the 27-year-old rapper filmed herself doing it and sent him to him.

She said: "I text him a video, and I was like, 'Hey, I'm burning your s**t. "I'm burning your things, so I don't know where you're at, probably with some girl, so I hope you get home quickly because I'm moving on, we're progressing on a spectrum of cheap to expensive.'"

Iggy recently admitted her life "fell apart" after they broke up and Nick had a daughter with his ex-girlfriend, Keonna Green, and she felt she needed to take some time for herself.

Iggy - who is finishing off her new LP Surviving the Summer - said: "It's no secret, I kind of had my personal life fall apart ... I needed a lot of time. I mean, you wake up one morning and your fiancé is having a baby with someone else, you're going to need some time, right? 

"I don't want to go and promote my album and get asked about my relationship that has just crumbled ... I just kind of felt like, on top of me needing the personal time, then feeling, 'Okay, I'm single now. I want to have sexy songs. I want to say stuff about being single'. I obviously didn't write that on my [original] album because when I wrote it I was about to get married."
