My eyes saw you and sent a warning   Straight to my brain   My heart started poundin' 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      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, 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 lightnin' flashin'   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      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   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
