Beyonce's Side-Swept Mermaid Waves, Plus More Celeb Beauty!

Thanks to the Kid's Choice Awards, iHeartRadio Music Awards, and a little somebody known as Karl Lagerfeld (because when he throws a party, the stars show up), our favorite celebrities were out in abundance this week. From a crazy-cool elaborate updo on Rihanna, to side-swept styles on Beyoncé and Brittany Snow, their A-game looks are inspiring our next trip to the salon.
