Lyrics
The Chipettes:
Shoo-ap-shoo-ah, shoo-ap-shoo-ah-ah-ah
(repeats in the background)
The Chipmunks:
You are mine, and you'll be to me
End of time, there's a love that's so
Genuine, I'll never let you go
The Chipettes:
In my heart, there's a place for you
When we're apart, no one else will do
It's in the cards, so I thought you should know
The Chipmunks & The Chipettes:
That I'll always be here (always)
To hold you near
You're my darling, you're my sweetest sugar pie
You are my heart, and everything else that's mine
You don’t depart, 'cause I don't even know what I'll do, ooh-ooh-ooh-ooh
