[Verse 2]                    
It's such a funny thing
How nothing's funny when it's you
You tell 'em what you mean
But they keep whiting out the truth
It's like a work of art
That never gets to see the light
Keep you beneath the stars
Won't let you touch the sky

Na na na na na na na na na
Na na na na na na na na na
I'm no beauty queen
I'm just beautiful me
Na na na na na na na na na
Na na na na na na na na na
You've got every right
To a beautiful life
C'mon

DWho (xx0232@1)says you're not star potential
GWho (320003@1)says you're not presidential
BmWho (x24432@1)says you can't be in movies
AListen (x02220@1)to me, listen to me
DWho (xx0232@1)says you don't pass the test
GWho (320003@1)says you can't be the best
BmWho (x24432@1)said, who said
AWon't (x02220@1)you tell me who said that 
Ayeah, (x02220@1)who said?

(you can do the D Dsus2 D Dsus4 instead of those two A's)

[Chorus x2]

Enjoy :)
