Christina Aguilera und Demi Lovato - Billboard Music Award 2018 

Estaba nerviosa a lado de esa tremenda cantante que es Christina Aguilera cualquier artista se pone asi al lado de esa diosa.

Demi was nervous, she was singing with her idol it's understandable

demi was nervous you can listen her voice kinda shaking

Christina also didnt have to hit a sustained A5 and then a sustained Bb5 soo... and christina was singing the easiest parts the whole time, demi was constantly doing a higher harmony and belting higher, because those were the parts they gave her, you should take that in concideration

because demis leg was broken

Girl on her worst day , she’s better than whatever fav you have that’s probably from recent years LMAOO good byeeeee girl

Perdon por ser humana y enfermarse ese dia?????' Imbecil ridiculo
