F           C 
  People say we shouldn't be together 
G                Am 
  We're too young to know about forever 
F          C                          G 
  But I say they don't know what they talk talk talking about  
F                C 
  Cause this love is only getting stronger 
G                  Am 
  So I don't wanna wait any longer 
F              C                          G 
  I just wanna tell the world that you're mine girl 
  
Oh
[Refrain]
                          F         C 
They don't know about the things we do 
                          G      Am 
They don't know about the I love you's 
                      F     C 
But I bet you if they only knew 
           G 
They would just be jealous of us 
                          F      C 
They don't know about the up all night's 
                            G      Am 
They don't know I've waited all my life 
                         F          C 
Just to find a love that feels this right 
     G 
Baby they don't know about 
  
They don't know about us
[Strophe]
F                   C 
(Just) one touch and I was a believer 
G              Am 
  Every kiss it gets a little sweeter 
F 
  It's getting better 
C                              G 
  Keeps getting better all the time girl

G                 Am 
  They don't know what you’ve done to my heart 
F              C 
  They can say anything they want 
      G 
Cause they don't know about us 
F                 C 
  They don't know what we do best 
         G                Am 
That's between me and you our little secret 
F 
  But I wanna tell 'em
