D5
You made me insecure
Told me I wasn't good enough
G5
But who are you to judge
When you're a diamond in the rough
B5
I'm sure you got some things
You'd like to change about yourself
G5
But when it comes to me
I wouldn't want to be anybody else

D5
Who says
Who says you're not perfect
                     G5
Who says you're not worth it
Who says you're the only one that's hurting
B5
Trust me
That's the price of beauty
                      G5
Who says you're not pretty
                      G5     A5
Who says you're not beautiful
D5

[Verse 2]
D5
It's such a funny thing
How nothing's funny when it's you
G5
You tell 'em what you mean
But they keep whiting out the truth
B5
It's like a work of art
That never gets to see the light
G5
Keep you beneath the stars
Won't let you touch the sky
D5
Na na na
Na na na
G5
I'm no beauty queen
I'm just beautiful me
D5
Na na na
Na na na
G5
You've got every right
To a beautiful life
C'mon

[Chorus]
D5
Who says
Who says you're not perfect
                     G5
Who says you're not worth it
Who says you're the only one that's hurting
B5
Trust me
That's the price of beauty
                      G5
Who says you're not pretty                 
Who says you're not beautiful
