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

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

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

[Verse 2]
[Zayn]
So c-come on,
anda 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 anda light up my world like nobody else,
The way that anda flip your hair gets me overwhelmed,
But when anda smile at the ground it ain't hard to tell,
anda don't know,
Oh oh,
anda don't know you're beautiful,
If only anda saw what I can see,
You'll understand why I want anda so desperately,
Right now I'm looking at anda and I can't believe,
anda don't know,
Oh oh,
anda don't know you're beautiful,
Oh oh,
That's what makes anda beautiful

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

[All]
anda don't know,
Oh oh,
anda don't know you're beautiful,

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

[Harry]
That's what makes anda beautiful
