NOTE: (Updated) Now, I finally know the lyrics! Hope tu amor it now!

FIRST VERSE:

tu can tell she's a princess
She doesn't need a crown
tu can tell she's a princess
She'll turn the world around...

tu can see it in her style
tu can see it in her smile
tu can see it in her flair
And the way she wears her hair

Spinning
Twirling
Girly!

CHORUS:

tu can tell she's a princess
She doesn't need a crown
tu can tell she's a princess
She'll turn the world around...

segundo VERSE:

The shoulders are back (Na, na, na)
You'll never see her slack (No, no, no)
And even if she falls (La, la, la)
She'll laugh and stand up tall (Yeah, yeah, yeah)

CHORUS:

tu can tell she's a princess (Yeah, yeah)
She doesn't need a crown (No, no)
tu can tell she's a princess (Yeah, yeah)
She'll turn the world around... (Yeah, yeah)

BRIDGE:

But the secret to her majesty
That sets the girl apart
Is the kindness that shows royalty
It's etched upon her heart
Oh, oh

CHORUS:

tu can tell she's a princess (You can see it in her style)
She doesn't need a crown (You can see it in her smile)
tu can tell she's a princess (You can see it in her flair)
She'll turn the world around... (And the way she wears her hair)

tu can tell she's a princess (You can see it in her style)
She doesn't need a crown (You can see it in her smile)
tu can tell she's a princess (You can see it in her flair-flair-flair)
She'll turn the world around...

This is the official lyrics. I MEAN IT!
