Bang Bang hitmaker Jessie J has revealed that the royalties from Miley Cyrus's hit Party In The USA paid her rent for years.

The 26-year-old singer penned the track for Cyrus's 2010 album Can't Be Tamed.

Speaking to Glamour magazine, Jessie said, "You've got to write songs, that's where the money is, being an artist. 'Party In The USA' paid my rent for, like, three years.

"Actually it was way longer than that. That's where I get most of my money. I write songs. I'm a singer. I love endorsements and stuff, but that's all added on."
