There's no doubt that Demi is a 22-year-old HAPPY "child" who's got the key to happiness. During her concert, she'd rather be holding an Olaf stuffed toy from the movie "Frozen" than picking up a bra.
Ahh! Olaf the snowman   "fainted" on the piano at→ 1:16 :) Girls threw their bras at→ 0:17 and at→ 0:33
Okay, on September 14th, Demi performed "Let It Go" at American Airlines Arena in Miami, Florida.
There are a lot of Brazilian girls in Miami. They're the only ones who know how to throw a bra at Demi.

Ok! The bras are not the most aerodynamic things in the world, but some girls love to throw them :)
 Did you know that a French scientist who spent 16 years studying hundreds of women’s breasts has come to the conclusion that bras are useless?  Ohh! I don't care about it because I've got small boobs.

Oh my goddess!! I can't breathe! Demi puts her amazing bikini body on display in Miami.

 ♪ Lyrics ↓↓ "Let It Go"
 
It's funny how some distance makes everything seem small
And the fears that once controlled me...can't get to me at all
Up here in the cold thin air I finally can breathe
I know I left a life behind, but I'm too relieved to grieve
Let it go, let it go...can't hold it back anymore
Let it go, let it go...turn my back and slam the door
And here I stand...and here I'll stay
Let it go, let it go...the cold never bothered me anyway
Standing frozen in the life I've chosen
You won't find me, the past is so behind me
