See, this is why she was there on stage last night after all these years. Her voice did improve a lot, her stage presence is always better than ever, her charisma, and the whole thing.
Although the song requires a lot of energy and dancing, she focused on her vocals a lot but still it was great in every way, but she showed RESPECT to this singing competition show by singing LIVE unlike some flop "singers".
When she was the it girl, not even a single artist could do half her success, and now that the music industry changed with new artists, which is normal, unlike many artists who are done, she is still here to stay as a successful artist and has so many things to deliver and all the girls from different generations are taking notes, starting from these musical shows judges.
Who else but the queen?
