If anyone knows how to make an entrance, it's Katy Perry [1]. On Sunday, the singer shone bright like the star that she is when she arrived at the Grammy Awards in LA. In addition to showing off her new platinum blond 'do, Katy opened up about her recent break from music to Ryan Seacrest [2], saying, "It's called taking care of your mental health," before seemingly shading Britney Spears [3] and making a joke about shaving her head [4]. Inside, Katy took the stage for a politically charged performance [5] alongside Skip Marley, and linked up with a handful of stars, including Chance the Rapper [6]. One thing's for sure: Katy had one hell of a night.
