I just found the lyrics to "That's how you know" from Disney's ENCHANTED.

SO COOL.

Giselle:
How does she know you love her?
How does she know she's yours?

Man:
How does she know that you love her?
Giselle
How do you show her you love her?
Both:
How does she know that you really, really, truely love her?
How does she know that you love her?
How do you show her you love her?
How does she know that you really, really, truely love her?

Giselle
It's not enough to take the one you love for granted
You must remind her, or she'll be inclined to say...
"How do I know he loves me?"
(How does she know that you love her?
How do you show her you love her?)
"How do I know he's mine?"
(How does she know that you really, really, truely love her?)

Well does he leave a little note to tell you you are on his mind?
Send you yellow flowers when the sky is grey? Heyy!
He'll find a new way to show you, a little bit everyday
That's how you know, that's how you know!
He's your love...

Man:
You've got to show her you need her
Don't treat your life, your mind leads her
Each day do something to need her
To believe you love her

Giselle
Everybody wants to live happily ever after
Everybody wants to know their true love is true...
How do you know he loves you?
(How does she know that you love her?
How do you show her you need her?)
How do you know he's yours?
(How does she know that you really, really, truely-)

Well does he take you out dancin' just so he can hold you close?
Dedicate a song with words in
Just for you? Oooo
All:
He'll find his own way to tell you
With the little things he'll do
That's how you know
That's how you know!
Giselle
He's your love
He's your love...

That's how you know
(la la la la la la la la)
He loves you
(la la la la la la la la)
That's how you know
(la la la la la la la la)
It's true
(la la la la la)

Because he'll wear your favourite colour
Just so he can match your eyes
Rent a private picnic
By the fires, glow-oohh
All:
His heart will be yours forever
Something everyday will show
That's how you know
(That's how you know)
That's how you know
(That's how you know)
That's how you know
(That's how you know)
That's how you know
(That's how you know)
That's how you know
(That's how you know)
That's how you know
(That's how you know)
That's how you know!

Giselle
He's your love...
Man:
That's how she knows that you love her
That's how you show you love her
Giselle
That's how you know...
Man:
You've got to show her you need her
Don't treat your mind, your mind leads her
Giselle
That's how you know...
Chorus:
How do you know that you love her?
That's how you know that you love her!
Giselle
He's your love...
Chorus:
It's not enough to take the one you love for granted!
