Baby check it out, I'm a star
Yeah, you heard right, I'm a star
(Verse 1)
My name is IU, you know I'm the best
So check it out, check it out
My style is unique, you know I'm the best
So check it out, check it out
(Pre-Chorus)
Everyone's looking at me, yeah
Trying to take my picture
I'm not a celebrity, I'm just like you
(Chorus)
So don't try to compare me to anyone
I'm a star, I'm a star
So don't try to compare me to anyone
I'm a star, I'm a star
(Verse 2)
I'm not like other girls, I'm not a model
I don't have any makeup, so what?
If you can't handle the truth, that's okay with me
You guys don't know what I've been through
So check it out
(Pre-Chorus)
Everybody looking at me, yeah
Trying to get a hold of me
I'm not a celebrity, I'm just like you
(Chorus)
So don't try to compare me to anyone
I'm a star, I'm a star
So don't try to compare me to anyone
I'm a star, I'm a star
(Bridge)
You guys think you know me? You don't know me at all
You guys think you love me? You don't love me at all
You guys think you know me? You don't know me at all
But you know what? I don't care about that at all
(Chorus)
So don't try to compare me to anyone
I'm a star, I'm a star (x2)
And that's how it is (x2)
Yeah, I'm the best (x2)
I am what I am (x2)
So check it out (x2)
Check it out (x2)
Check it out (x2)
Check it out now! (x2)
Yeah! (x2)
