Want your rent paid for three years? Write a hit song like Jessie J! Miley Cyrus may have recorded "Party In The USA," but Jessie J is the one who wrote it.

In an interview with Glamour UK, Jessie looks back on her career as a songwriter before hitting it big with her own solo career. She tells the magazine:

"'Party in the USA' paid my rent for, like, three years. Actually it was longer than that. That's where I get most of my money.  I write songs.  I'm a singer.  I love doing endorsements and stuff, but that's all added on."

Keep the amazing songs coming, Jessie!
