Baby, baby, baby, didn't believe in love at all
Went through my days with a wall in place
Baby, baby, baby fine, I'll be stronger on my own
But then you came along and I've changed

Yes I feel the butterflies
Yes I go weak inside
Hate admit it, but I'm hit and
I don't want you to leave my side

Used to laugh at romantic films
Now I see you and me in them
Saying cheesy lines like
I'll be yours if you'll be mine

This must be love
Look what you do to me (what you do to me)
Oh, what you do to me (what you do to me)
Can't get enough
Of what you do to me (what you do)
Oh, what you do to me (what you do)
Put your hands up if you feel like this
If you're crazy 'bout a guy and it's real like this
Put your hands up if you feel like this
If you're crazy 'bout a girl and it's real like this

Baby, baby, baby, 
I've been spraying your cologne on my clothes
Have I got insane?
Maybe, maybe, maybe
I was way too cynical
Thinking I would never fall
Now I'm craving

Roses used to make me quease
But from you the smell's so sweet
Hate to admit it, but I'm here
And I kinda even like your feet

Never had a boy get me so
Your pictures under my pillow
Girl you offer silly names
My boo, my baby-cakes

This must be love
Look what you do to me (what you do to me)
Oh, what you do to me (what you do to me)
Can't get enough
Of what you do to me (what you do)
Oh, what you do to me (what you do)
Put your hands up if you feel like this
If you're crazy 'bout a guy and it's real like this
Put your hands up if you feel like this
If you're crazy 'bout a girl and it's real like this

I was ashamed, embarrassed to feel
Head over heels
Thought love was just fantasy
Now with you, I don't have to hide
You bring me to life
I never knew, oh

If you're crazy 'bout a guy and you feel like this, hey
Put your hands up if you feel like this
Put your hands up if you feel like this
(Like this, like this, like this, like this, like this, like this, like this, like this)

This must be love
Look what you do to me (what you do to me)
Oh, what you do to me (what you do to me)
Can't get enough
Of what you do to me (what you do)
Oh, what you do to me (what you do)
Put your hands up if you feel like this
If you're crazy 'bout a guy and it's real like this
Put your hands up if you feel like this
If you're crazy 'bout a girl and it's real like this
(like this, like this, like this, like this, like this)
