Iggy Azalea has supported Britney Spears because she'd want her friends to "back [her] up" in the same situation

Now, she told PEOPLE: "I know her and love her. She's such an icon and inspiration and was so kind to me that if I could help her in any way that I can, then I want to do that.

"I never said anything before because I really wanted to respect her privacy but after she spoke, I just thought if I were in her shoes, I would want my friends to back me up.

"I felt like, you know what? Regardless of what people might think about it, I have to say something."

Last week, the 'Fancy' singer claimed Britney's father made her sign a non-disclosure agreement (NDA) "moments" before the two singers were due on stage.

She wrote in a statement shared to Twitter: "Its basic human decency to at the very least remove a person Britney has identified as abusive from her life. This should be illegal.

“During the time we worked together in 2015, I personally witnessed the same behaviour Britney detailed in regards to her father last week and I just want to back her up & tell the world that: She is not exaggerating or lying.

"I saw her restricted from even the most bizarre and trivial things:

like how many sodas she was allowed to drink. Why is that even necessary?(sic)"

Iggy then took a swipe at Britney's father Jamie Spears - who the 'Womanizer' hitmaker has unsuccessfully attempted to have removed as her co-conservator - and the way he behaved towards her ahead of the two stars singing 'Pretty Things' at the 2015 Billboard Music Awards.

She continued: “Her father conveniently waited until literally moments before our BMAs performance when I was backstage in the dressing room & told me if I did not sign an NDA he would not allow me on stage.

“The way he went about getting me to sign a contract, sounded similar to the tactics Britney spoke about last week in regards to her Las Vegas show.

"Jamie Spears has a habit of making people sign documents while under Duress it seems, and Britney Spears should not be forced to co-exist with that man when she’s made it clear it is negatively impacting her mental health. This is not right at all.(sic)"

Iggy's statement came a few days after she urged fans to "leave [her] alone" after they accused her of not supporting Britney and admitted she was worried about being sued if she did decide to speak out.
