[Zayn]
Girl it should be me, driving to your house
Knocking on your door, kissing you on the mouth

[Liam]
Holding on your hand, dancing in the dark
'Cause I was the only one who loved you from the start

[Harry]
But now when I see you with him
It tears my world apart... because

[All]
I've been waiting
All this time to finally say it
But now I see your heart's been taken
And nothing could be worse.
Baby, I loved you first.
Had my chances,
Could've been where he is standing.
That's what hurts the most.
Girl, I came so close
But now you'll never know,
Baby, I loved you first.

[Louis]
Girl it should be me, calling on your phone
Saying you're the one and I'll never let you go

[Harry]
I never understood what love was really like
But I felt it for the first time looking in your eyes

[Liam]
But now when I see you with him
My whole world falls apart... because

[All]
I've been waiting
All this time to finally say it
But now I see your heart's been taken
And nothing could be worse.
Baby, I loved you first.
Had my chances,
Could've been where he is standing.
That's what hurts the most.
Girl, I came so close
But now you'll never know,
Baby, I loved you first.

[Zayn]
First touch, first kiss,
First girl who made me feel like this…
Heartbreak, it's killing me,
I loved you first ‒ why can't you see?

[Niall]
I've been waiting
All this time to finally say it
But now I see your heart's been taken
And nothing could be worse.

[Zayn]
Baby I loved you first!

[All]
Had my chances
Could've been where he is standing
That's what hurts the most
Girl I get so close but now you'll never know
Baby I loved you first…

[Zayn]
Baby I loved you first…
Baby I loved you first…
Oh yeah...

[All]
Baby I loved you first
