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
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
All:
It's in his DNA, D-D-D-DNA
It's in his DNA
And he just takes my breath away, b-b-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-DNA
Jesy:
It's the blue in his eyes that helps me see the future
Fingerprints that leave me covered for days, yeah hey 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 woah
Jade:
And my heart won't beat again
If I can't feel him in my veins
No need to question, I already know
All:
It's in his DNA, D-D-D-DNA
It's in his DNA
And he just takes my breath away, b-b-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-DNA
Leigh-Anne:
It's all about his kiss, contaminates my lips
Our energy connects, it's simple genetics
I'm the X to his Y, it's the colour of his eyes
He can do no wrong, no he don't need to try
Made from the best, he pa**es all the tests
Got my heart beating fast, it's cardiac arrest
He's from a different strain that science can't explain
I guess that's how he's made, in his D-D-D-DNA
All:
Aah, Aah, Aah, Aah...
Perrie:
Oh woah woah woahh, ohh
All:
It's in his DNA, D-D-D-DNA
It's in his DNA
And he just takes my breath away, b-b-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-DNA
