The Australian rapper, 26, admitted that she isn’t a natural bottom shaker: “I did a lot of rehearsals actually, and man I lost 15 pounds in a week dancing to that song!”

Speaking about the gruelling video shoot for comeback track, Mo Bounce, Azalea explained: “It’s a lot — I went on a meal plan before the video because I knew I would have to be dancing fairly skimpily dressed.”

But despite telling New Zealand radio that “it just has to come naturally”, Azalea did confess to having had a little help.

“I did take classes. I do have someone who is very, very good at twerking and she helped me. I never realised how flexible you have to be to do that stuff,” she said.

When quizzed on her top twerking tips, Azalea told listeners: “My teacher was like ‘I really suggest you take yoga’ and I didn’t know you had to take yoga to be a twerker but apparently you do.”

It’s not the first time that Azalea has flashed flesh. She famously stripped down with Jennifer Lopez for their Booty video, and even squeezed J. Lo’s iconic derrière.

Iggy rose to fame in 2014 after releasing the global smash hit, Fancy, and touring with Beyonce.

The controversial rapper went on to collaborate with some of the hottest artists in the industry including Jennifer Hudson, Rita Ora and Ariana Grande.

Her return to the charts comes after fan backlash, accusations of racism and cultural appropriation, and mediocre sales for her last release, Team, and Britney collaboration, Pretty Girls.
