SuPer quiCk translation 2 english plzz (very very short!) "Mi TeSoRo"

Just a very quick phrase

nada me importa lo que me digan
si yo te quiero si yo te adoro
por eso grito a todo el mundo
que tu eres mi tesoro que tu
eres mi tesoro

I don't care what people tell me
because I love you and I adore you
that's why I'm shouting to the world
that you are my treasure
you are my treasure.

whos that song by?
