Iggy Azalea thinks Twitter is ''unfortunate''.

The 28-year-old rap star is well-known for her candid posts on the micro-blogging platform, but Iggy admits that there's a downside to giving her fans a behind-the-scenes look into her personal life.

She shared: ''Twitter is unfortunate, social media is unfortunate because it freezes that in time for us.

''In some ways, that's good. You can look back and self reflect and say, 'Geez, I've come a long way, that's good.' The silver lining is that you can look at that and be like, 'Never again.'

''But I don't really sit around thinking, 'If only I could delete that one thing.' You know, you've gotta move forward and have personal growth. I don't really think much about that.''

Meanwhile, Iggy admitted the landscape of rap music has changed markedly since she launched her breakthrough hit 'Fancy' in 2014.

The blonde beauty revealed she's made a conscious effort to adapt while still trying to remain ''original''.

Iggy told Idolator: ''I watch what is going on, because it's important - no matter what it is you're doing, if you're rapping or working in an office - it's important to keep an eye on what is happening around you. So I watch what's going on and what people like, but I never want to try to copy that. I still want to be original and have a sound that's true to me.

''So for me, I listen to what's happening or what's changing sonically, and then I just try to incorporate something that's organic to me.''

Iggy admitted she's always trying to evolve as an artist.

She said: ''I like to pay attention and then figure out, how do I fit into this world organically? How do I evolve as an artist from 2013 to 2018 and still sound like me?''
