In response to one negative comment, the Mo Bounce rapper wrote: 'He just turned 23, he's five years younger than I am.

'Is that unusual to you? Because almost everyone I know isn't the exact age as the person they date.

'You all act like he's some little kid that just left school or I'm some old ass woman. We are both in our twenties, get off my nuts.'

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

During an interview with Watch What Happens Live in March last year, Iggy revealed she destroyed all of Nick's belongings following their bitter split.

'I burnt it all, darling. Every designer you could think of, I’ve burned,' she told the TV program, as reported by People.

Prior to her relationship with Carti, Iggy enjoyed a short-lived fling with American footballer DeAndre Hopkins, 27, with the two splitting last August.
