NOTE: (Updated) Now, I finally know the lyrics! Hope あなた 愛 it now!

FIRST VERSE:

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

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

Spinning
Twirling
Girly!

CHORUS:

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

秒 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:

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

あなた 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)
あなた 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)

あなた 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)
あなた 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!
