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

FIRST VERSE:

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

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

Spinning
Twirling
Girly!

CHORUS:

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

SECOND 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:

You can tell she's a princess (Yeah, yeah)
She doesn't need a crown (No, no)
You 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:

You 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)
You 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)

You 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)
You 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!
