Happy birthday sweet sixteen

Tonight's the night I've waited for
Because you're not a baby anymore
You've turned into the prettiest girl
I've ever seen
Happy birthday sweet sixteen

What happened to that funny face
My little tomboy
Now wears satin and lace
I can't believe my eyes
You're just a teenage dream
Happy birthday sweet sixteen

When you were only six
You had a big brother
Then when you were ten
You didn't like each other
When you were thirteen
You were my funny valentine
But since you've grown up
Your future is sewn up
From now on you're gonna be fine

So if I should smile with sweet surprise
It's just that you've grown up
Before my very eyes
You've turned into the prettiest girl
I've ever seen
Happy birthday sweet sixteen

If I should smile with sweet surprise
It's just that you've grown up
Before my very eyes
You've turned into the prettiest girl
I've ever seen
Happy birthday sweet sixteen
