This is guaranteed to go straight to the top of the charts!

Iggy Azalea just let the cat out of the bag that she and Britney are collaborating on a new song! "We have a song, which is going to be her first single, coming out next year," the rapper told KISS 108. "I still haven't really got to have a conversation with her, so I'm hoping New Year's will be the time I can get her in a corner," she added.

So how did this come about? "She said she would like to work with me in an interview and they reached out. We recorded a few different things and then one of those just ended up being, I think, undeniably great. Hopefully everybody will get to hear it at the beginning of next year. I think people are really going to love and enjoy it. It's a really fun track," she revealed.

We can't wait to hear it!
