My eyes saw you and sent a warning straight to my brain
My heart started pounding in my chest
Like a runaway train
I felt my hands start to sweat
And my knees start to buckle
A shiver down my spine
And I knew I was in trouble
Never dreamed forever could've ever
Fell together like this

CHORUS:
All it took was one kiss one touch
Like a long line of dominoes
I'm fallin' in love
It's a physical, spiritual, chemical strong attraction
Girl you've started an unstoppable chain reaction

The way you smile at me
It ignites an undeniable spark
The way you walk through a room
It's enough to make a fire start
Like the lightning flashing
Then the thunder rollin'
I'll follow you wherever you're goin'
Now I've got a reason for believin' in a feelin' like this

CHORUS 2x

Girl you've started an unstoppable chain reaction
Girl you've started an unstoppable chain reaction
Girl you've started an unstoppable chain reaction
