10. Katy Perry – 2015 Grammy Awards

Just right after her amazing Super Bowl performance, Katy Perry came out roaring at the 2015 Grammy Award show in her purple short locks. While speaking to Ryan Seacrest, the 31-year-old said she wanted to “shine bright like a diamond.” She was definitely shining with her extra, crystal-embellished dress by Zuhair Murad which was fresh off the Paris Couture Runway and she worked it. Everyone was digging her purple ‘do, but it turned out to be just a wig as the pop star switched it to a more settled pony-tail look for her performance that night. Not to worry, Katy went back to her purple hair for the after party. Apparently, she was digging it too.
