Is it me or her voice has changed a bit ?

Her voice has significantly improved, yes.

She got a vocal coach who's worked wonders on her support, mix and vibrato.

The performance was great too.

Since it's a positive thread, no one will enter tho

her voice is so much more resonant now

Right? This year has been a blessing for her voice.

That was... amazing. Her voice is 1000x better this year, omg.

I'm honestly not sure if I like the new voice more. Yes it's good and her control on it is great

BUT when an artist gets vocal coaching, and this is quite evident here, Demi is using all the methods she was taught; in particular you can see her trying to fully spit the words, and that kinda just feels... IDK less personal?

Great performance nonetheless. I just prefer an artist singing from the heart than being perfect. that's what a studio version is for.

She was really sweet with that little girl

That was good. She was really sweet to the girl too
