(Paul Brandt/Josh Leo/Rick Bowles) 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 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 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 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 Girl you've started an unstoppable chain reaction Girl you've started an unstoppable chain reaction Girl you've started an unstoppable chain reaction
