Britney Spears and Iggy Azalea were seen getting all kinds of '80s on the set of their new single, "Pretty Girls," back in April, and now the song has arrived! It was leaked on Saturday morning and has since been officially released on Britney Spears's Vevo YouTube account. It's upbeat, and it's . . . definitely a song. Honestly, I was hoping for more when these two powerhouses announced a collaboration. Maybe this will satisfy die-hard fans, and maybe it'll win me over when the two perform it at the Billboard Music Awards on May 17. Listen below.
