EYou (022100@1)made me insecure
Told me I wasn't good enough

C#mBut (x13321@4)who are you to judge
When you're a diamond in the rough

AI'm (x02220@1)sure you got some things
You'd like to change about yourself

BBut (x2444x@1)when it comes to me
I wouldn't want to be anybody else

ENa (022100@1)na na
Na na na

C#mI'm (x13321@4)no beauty queen

To a beautiful life

[Chorus]

EWho (022100@1)says
Who says you're not perfect

C#mWho (x13321@4)says you're not worth it
Who says you're the only one that's hurting

ATrust (x02220@1)me
That's the price of beauty

BWho (x2444x@1)says you're not pretty
Who says you're not beautiful
Who says

E (022100@1)EIt's (022100@1)such a funny thing
How nothing's funny when it's you

C#mYou (x13321@4)tell 'em what you mean
But they keep whiting out the truth

AIt's (x02220@1)like a work of art
That never gets to see the light

BKeep (x2444x@1)you beneath the stars
Won't let you touch the sky

ENa (022100@1)na na
Na na na
