So much happened this Saturday – Kate Middleton gave birth, the Kentucky Derby, the Mayweather vs. Pacquiao fight – that you might have might the official release of one of the biggest collaborations of the year. Luckily, you didn’t miss much. Britney Spears and Iggy Azalea teamed up for a girl power anthem that falls flat, to say the very least. We saw pics of their 80’s-inspired music video for the song that got us excited, but now that we’re finally hearing the song, we’re hoping someone else steps up with a summer anthem. It’s certainly no “Toxic” or “Baby One More Time.” [youtube https://www.youtube.com/watch?v=Bqj-ab_H9KU&w=640&h=360]
