Her fellow Voice coach Blake Shelton called the diva, “One of the greatest female vocalists of all time,” and she is the second top-selling single artist of the 2000s, behind Madonna.

Christina’s hit singles like “Beautiful,” “Fighter,” and “Ain’t No Other Man” have been featured on shows like Glee and Smash, not to mention music competitions shows like The Voice.
