[Verse 1]
Baby, baby, baby, didn't believe in love at all
Went through my days with a wall in place
Baby, baby, baby, thought I'd be stronger on my own
But then you came along and I'm changed

[Refrain]
Yes, I feel the butterflies
Yes, I go all weak inside
Hate to 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
Say cheesy lines like "I'll be yours
If you'll be mine"

[Pre-Chorus]
This must be love
Look what you do to me, oh, what you do to me
Can't get enough
Of what you do to me, oh, what you do to me

[Chorus]
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
[Verse 2]
Baby, baby, baby, I've been sprayin' your cologne
On my clothes, have I gone insane?
Maybe, maybe, maybe I was way too cynical
Thinking I would never fall, now I'm craving

[Refrain]
Roses used to make me quease
But from you, they smell so sweet
Hate to admit it, but I'm hit
And I kinda even like your feet
Never had a boy get me so
Your pictures under my pillow
God you offer silly names
My boo, my babycakes

[Pre-Chorus]
This must be love (This must be love)
Look what you do to me, oh, what you do to me
Can't get enough (Ooh, yeah)
Of what you do to me (What you do), oh, what you do to me (What you do to me, yeah)

[Chorus]
Put your hands up if you feel like this (Put your hands up)
If you're crazy 'bout a guy and it's real like this (Yeah, yeah, ay)
Put your hands up if you feel like this (Ay)
If you're crazy 'bout a girl and it's real like this (Like this)
[Bridge]
I was ashamed, embarrassed to feel
Head over heels, thought love was just fantasy
But now with you, I don't have to hide
You bring me to life, I never knew, oh, oh

[Drop]
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 (Put your hands up)
Like this, like this, like this, like this
Like this, like this, like this, like this (This must be love)

[Pre-Chorus]
This must be love (This must be love)
Look what you do to me, oh, what you do to me
Can't get enough (Ooh, yeah)
Of what you do to me (What you do), oh, what you do to me (What you do to me, yeah)

[Chorus]
Put your hands up if you feel like this (Put your hands up if you feel like this)
If you're crazy 'bout a guy and it's real like this (If you feel like this, if you feel like this, yeah)
Put your hands up if you feel like this (Ay)
If you're crazy 'bout a girl and it's real like this (Like this)

[Outro]
Like this, like this, like this, like this
