Iggy Azalea has apologised for homophobic comments she made "as a young person".

The 'Fancy' rapper has decided to pull out of a scheduled performance at Pittsburgh Pride concert on 13 June following criticism of her booking, due to her previous homophobic comments on Twitter, admitting she "deeply regrets" the things she has "carelessly" said in the past.

She wrote: "I am truly disappointed I have to share this news, but I will no longer be performing at Pittsburgh Pride on June 13th. This has been a difficult decision as I truly support the event and LGBTIQA communities, however I feel my participation at this point would only serve to further distract from the true purpose of the event (sic)."

The 25-year-old musician went on to declare she is a "firm" believer of "equality" and would never use the comments as an "adult".

She continued: "I am a firm believer in equality. Unfortunately in the past as a young person, I used words I should not have. The last thing I want is for something so carelessly said to be interpreted as reflective of my character. I meant no harm and I deeply regret ever uttering those words. As an adult I would never used them because I understand they play a detrimental role in the fight for issues I do truly believe in.

"I am sorry to anyone I have offended or disappointed & I wish all my fans and family participating in Pride the best of luck (sic)."
