My version is without the part of Joe Jonas. The song basically is complete even 
with the absence of the guy part.  My voice students are using this arrangement.

THIS IS REAL

Intro:  C  F    G/C   C

              C                F                G
I've always been the kind of girl, that hid my face, 
     C                  F                      G
So afraid to tell the world, what I've got to say, 
       C          F/A    C              G
But I have this dream, bright inside of me, 
           F                
I'm gonna let it show, it's time,
                             G
to let you know, to let you know, 

CHORUS:
         F             C
This is real, this is me, 
                         F
I'm exactly where I'm supposed to be now, 
                C     F        G
Gonna let the light, shine on me, 
            F         C
Now I've found who I am, 
                          F
There's no way to hold it in,
C                          F         G(Hold)  C   F/C  G/C   C 
No more hiding who I wanna be,     This is me

        C               F                      G
Do you know what it's like, to feel so in the dark? 
     C            F                               G
To dream about a life, where you're the shining star, 
        C       F/A         C            G
Even though it seems, like it's too far away, 
    F                                        G
I have to believe, in myself, it's the only way,
