How do I Know If I’m In Love

Is there a doctor or a book on a shelf?
Give me some wisdom please, I need some help
I know that science, but I just can't read
The way she smiles, laughs, the way she speaks to me
I'm going all outta my mind, I'm a-falling deep

Well, you got my heartbeat beating outta my chest
The butterflies are flying, ooh, I'm a mess
Wouldn't it be sweet if you're the one for me?
But how do I know if I'm in love?
Well, how do I know if I'm in love?
With you, baby

Well, I get this funny feeling when she holds my hand
I love the way she says that I'm her man
I know that there are signs, but I just can't believe
The way she smiles, laughs, the way she says she loves me
She's coming on strong like a fever in the night

Well, you got my heartbeat beating outta my chest
The butterflies are flying, ooh, I'm a mess
Wouldn't it be sweet if you're the one for me?
But how do I know if I'm in love?
Ah, let's go, cap

Well, you got my heartbeat beating outta my chest
The butterflies are flying, ooh, I'm a mess
Wouldn't it be sweet if you're the one for me?
But how do I know if I'm in love?
Well, how do I know if I'm in love?
Well, how do I know if I'm in love?
Alright, alright now
