Pretty girls make pretty music -- and sometimes, that music gets stolen.
Iggy Azalea and Britney Spears' collab "Pretty Girls" was leaked early Saturday morning. The song, which will be featured on Britney's upcoming ninth studio album, has already made it to the airwaves on a few radio stations.
The sunny jam is definitely going to be a summer anthem, but this wasn't the version of the collab that the pop stars wanted you to hear.

Wondering what's going on with "Pretty Girls" campy space theme and those very '80s outfits on Britney and Iggy? It makes more sense than you think -- the music video pays homage to the 1998 cult classic Earth Girls are Easy, starring Geena Davis and Jeff Goldblum.
According to Brit, the throwback vid, filmed last month in Studio City, Calif., features one of her fave dance scenes ever!
"Pretty Girls" will make it's TV debut when Iggy and Britney perform at the 2015 Billboard Music Awards on May 17. Here's to hoping Brit's ankle injury is healed by then!
