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

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, yeah

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 rolling
I'll follow you wherever you're going
Now I've got a reason for believing in a feeling like this

And 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

And all it took was one kiss one touch
And 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

Girl, you've started an unstoppable, started an unstoppable
Started an unstoppable chain reaction, yeah
