[Verse 1]
[Liam]
You're insecure,
Don't know what for,
You're turning heads when آپ walk through the door,
Don't need make-up,
To cover up,
Being the way that آپ are is enough,

[Bridge]
[Harry]
Everyone else in the room can see it,
Everyone else but you,

[Chorus]
[All]
Baby آپ light up my world like nobody else,
The way that آپ flip your hair gets me overwhelmed,
But when آپ smile at the ground it ain't hard to tell,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,
If only آپ saw what I can see,
You'll understand why I want آپ so desperately,
Right now I'm looking at آپ and I can't believe,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,
Oh oh,
That's what makes آپ beautiful

[Verse 2]
[Zayn]
So c-come on,
آپ 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 eye eye eyes,

[Bridge]
[Harry]
Everyone else in the room can see it,
Everyone else but you,

[Chorus]
[All]
Baby آپ light up my world like nobody else,
The way that آپ flip your hair gets me overwhelmed,
But when آپ smile at the ground it ain't hard to tell,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,
If only آپ saw what I can see,
You'll understand why I want آپ so desperately,
Right now I'm looking at آپ and I can't believe,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,
Oh oh,
That's what makes آپ beautiful

Na Na Na Na Na Na Naaa,

[Middle 8]
[Harry]
Baby آپ light up my world like nobody else,
The way that آپ flip your hair gets me overwhelmed,
But when آپ smile at the ground it ain't hard to tell,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,

[Chorus]
[All]
Baby آپ light up my world like nobody else,
The way that آپ flip your hair gets me overwhelmed,
But when آپ smile at the ground it ain't hard to tell,
آپ don't know,
Oh oh,
آپ don't know you're beautiful ([Zayn:] Oh),
If only آپ saw what I can see,
You'll understand why I want آپ so desperately ([Zayn:] Desperately),
Right now I'm looking at آپ and I can't believe,
آپ don't know,
Oh oh,
آپ don't know you're beautiful,
Oh oh,
آپ don't know you're beautiful,
Oh oh,

[Harry]
That's what makes آپ beautiful
