[Verse 1: Liam]
You're insecure, don't know what for
You're turning heads when you walk through the door
Don't need makeup to cover up
Being the way that you are is enough
[Pre-Chorus: Harry]
Everyone else in the room can see it
Everyone else but you
[Chorus: All & Harry]
Baby you light up my world like nobody else
The way that you flip your hair gets me overwhelmed
But when you smile at the ground it ain't hard to tell
You don't know, oh oh, you don't know you're beautiful
If only you saw what I can see
You'll understand why I want you so desperately
Right now I'm looking at you and I can't believe
You don't know, you don't know you're beautiful
That's what makes you beautiful
[Verse 2: Zayn]
So c-come on, you got it wrong
To prove I'm right I put it in a song
I don't know why you're being shy
And turn away when I look into your eyes
[Pre-Chorus: Harry]
Everyone else in the room can see it
Everyone else but you
[Chorus: All & Harry]
Baby you light up my world like nobody else
The way that you flip your hair gets me overwhelmed
But when you smile at the ground it ain't hard to tell
You don't know, oh oh, you don't know you're beautiful
If only you saw what I can see
You'll understand why I want you so desperately
Right now I'm looking at you and I can't believe
You don't know, you don't know you're beautiful
That's what makes you beautiful
[Bridge: All & Harry]
Nana nana nana nana, nana nana nana nana, nana nana nana nana
Baby you light up my world like nobody else
The way that you flip your hair gets me overwhelmed
But when you smile at the ground it ain't hard to tell
You don't know, oh oh, you don't know you're beautiful
[Chorus: All & Harry]
Baby you light up my world like nobody else
The way that you flip your hair gets me overwhelmed
But when you smile at the ground it ain't hard to tell
You don't know, oh oh, you don't know you're beautiful
If only you saw what I can see
You'll understand why I want you so desperately
Right now I'm looking at you and I can't believe
You don't know, you don't know you're beautiful
That's what makes you beautiful
