She is getting to be blasé and must find new ways to stay in the spotlight like many people in the spotlight do as they fade.
She is getting old at 33 for a teenage audience. Plus putting on weight in her thighs.
She cannot sing so her performance is like too many others where they have dancers and fireworks and lights to distract you. She will be replaced with a younger version of herself as there are only 6 media companies that control 90% of what we see and hear and they need new faces all the time.
