She couldn't hide her excitement and immediately tweeted her thanks to her fans.
Woah, I can't believe this experiment worked. Thank you so much for making my album number 1!
The album contains the lead single "Chandelier" and track off The Hunger Games soundtrack "Elastic Heart".
But she's not the only Aussie woman tearing up the US music scene.... Iggy Azalea's "Fancy" is still Number 1 on the US Billboard Hot 100 singles chart.
So congratulations to these Australian musicians on top of the pop world right now.
