Most of the work was done for me. Took some advice from another tabs   comments 
and I have just made a few slight changes and it sounds better to   me when I sing 
with it. With and without song in background.

 C                               Am
 She's just a girl, and she's on fire
F                      G    
Hotter than a fantasy, lonely like a highway
C                                    Am
She's living in a world, and it's on fire
F                        G 
Filled with catastrophe, but she knows she can fly away

C   Am                       Em
Oh, she got both feet on the ground
                     G  
And she's burning it down
C   Am                      Em     
Oh, she got her head in the clouds
                      G
And she's not backing down

                G
This girl is on fire
Em              Am 
This girl is on fire
C                G
She's walking on fire
Em              Am   C 
This girl is on fire 

C                              Am
Looks like a girl, but she's a flame
F                                
So bright, she can burn your eyes
G                            
Better look the other way
C                                       Am
You can try but you'll never forget her name
F          
She's on top of the world
G
Hottest of the hottest girls say

C   Am                     Em
Oh, we got our feet on the ground
                     G  
And we're burning it down
C   Am                  Em 
Oh, got our head in the clouds
                     G
And we're not coming down

                G
This girl is on fire
Em              Am
This girl is on fire
C                G

Em              Am   C
This girl is on fire

F                             G
Everybody stands, as she goes by
                                           F
Cause they can see the flame that's in her eyes
                                     G
Watch her when she's lighting up the night
                          Am 
Nobody knows that she's a lonely girl
           Em 
And it's a lonely world
                    F           C     G
But she gon' let it burn, baby, burn, baby

                G
This girl is on fire
Em              Am
This girl is on fire
C                G 
She's walking on fire
Em              Am   C
This girl is on fire

G  Em   Am     C  
Oh,     oh,    oh
G  Em   Am     C     
Oh,     oh,    oh
G  Em   Am     C
Oh,     oh,    oh
G  Em   Am     C
Oh,     oh,    oh

She's just a girl, and she's on fire
