[Intro: All]
It's in his DNA
It's in his DNA

[Verse 1 : Perrie]
Does he tell you he loves you when you least expect it?
Does he flutter your heart when he kisses your neck?
No scientist or biology
It's obvious, when he's holding me
It's only natural that I'm so affected

[Pre-Chorus: Jade]
Oh, and my heart won't beat again
If I can't feel him in my veins
No need to question, I already know

[Chorus: All]
It's in his DNA
And he just takes my breath away
It's in his DNA
And he just takes my breath away
It's in his DNA
D-D-D-DNA, it's in his DNA
And he just takes my breath away
Bre-bre-bre-breath away
I feel it every day
And that's what makes a man
Not hard to understand
Perfect in every way
I see it in his face, nothing more to say
It's in his D-D-D-D-DNA
[Verse 2: Jesy]
It's the blue in his eyes that helps me see the future
Fingerprints that leave me covered for days, yeah, yeah
Now I don't have any first degree
But I know what he does to me
No need to work it out, it's so familiar, oh

[Pre-Chorus: Jade]
And my heart won't beat again
If I can't feel him in my veins
No need to question, I already know

[Chorus: All]
It's in his DNA
And he just takes my breath away
It's in his DNA
And he just takes my breath away
It's in his DNA
D-D-D-DNA, it's in his DNA
And he just takes my breath away
Bre-bre-bre-breath away
I feel it every day
And that's what makes a man
Not hard to understand
Perfect in every way
I see it in his face, nothing more to say
It's in his D-D-D-D-DNA
[Instrumental Break]

[Chorus: All]
It's in his DNA
And he just takes my breath away
It's in his DNA
And he just takes my breath away
It's in his DNA
D-D-D-DNA, it's in his DNA
And he just takes my breath away
Bre-bre-bre-breath away
I feel it every day
And that's what makes a man
Not hard to understand
Perfect in every way
I see it in his face, nothing more to say
It's in his D-D-D-D-DNA
