Iggy Azalea refused to dance in her new music video because she thought it would be ''obnoxious''.

The 'Fancy' hitmaker was encouraged by her 'Pretty Girls' collaborator Britney Spears to join her and perform a little number during their music video but she politely declined.

She said: ''I didn't dance! She wanted me to. Since I was co-directing the video, the way I explained it was, it would be kind of obnoxious for me to direct a video and give myself a dance break as well.

''Like, 'Here's the video! And I gave myself a dance scene!' I don't know if it necessarily fits my identity, but I think Britney's identity is really embedded in being a dancer, and that's something she really wanted to do as well. So there's a lot of dancing in the video, but I wouldn't say it's centred around that.''

And the 24-year-old singer also let slip a few details about the highly anticipated video, revealing it is inspired by the 1980s.

She told USA Today: ''You know me, I like having a narrative. So if it was just like, '80s!' that would be kind of boring for me. But what Britney made clear to me is that she really wanted to do a video where she got to dress up and play a character.

''I think Geena Davis just like the ultimate '80s pin-up hot, cool type of girl, so I told Britney to check her out, and she was like, 'Yes, I love Geena Davis!' So we based our characters on a lot of stuff like that. But there's definitely a narrative. I don't want to give it away, but it's quirky and funny.''
