[Verse 1: Tinchy Stryder, Tinchy Stryder & Dappy]
It was nothin' but a quick thing
Kid's games, kiss chase, just a quick fling
Now I'm hopin' you never go missin'
Now I'm tellin' you, you can hold this ring, watch how it glistens
Thought it would be done as quick as the wind blows
Didn't think I would ever be involved
So I even wrote a song called "Don't Go"
Now it's just you and me on a love road
We done it like D-low, us two tiptoe, duck, dive, get low
And now I care less about who knows
Now we're deep in, way past intros
Dappy, explain though
[Pre-Chorus: Dappy & Tinchy Stryder]
See never did I think a boy like me would be in need
When all I really wanted was to have some fun
Now I'm losing my hеad, I'm telling you one thing (Oh-oh)

[Chorus: Dappy & Tinchy Stryder]
You're numbеr one
See, I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)
See, I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)

[Post-Chorus: Dappy]
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Number one
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Number one
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Number one
[Chorus: Dappy]
Number one
I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)
See, I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)

[Post-Chorus: Dappy]
Oh-oh-oh-oh

[Verse 2: Tinchy Stryder, Tinchy Stryder & Dappy]
Yo, it was all now, never planned no after
It was like games, jokes, laughter
Live for the moment, left it all open
Now I’m in deep, flames, lava, breathe, calmer
And now I’m statin'
See, I never saw this in my daydream
It's really you that I’m fully ratin'
And the day's here, no more waitin'
Played it all wise 'cause a smart man raised him
I was all hurt, pain, achin'
On the wrong path, then a good girl saved him
That’s why I'm lettin' her know she’s amazin'
[Pre-Chorus: Dappy & Tinchy Stryder]
See never did I think a boy like me would be in need
When all I really wanted was to have some fun
Now I'm losing my head, I'm telling you one thing (Oh-oh)

[Chorus: Dappy & Tinchy Stryder]
You're number one
See, I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)

[Post-Chorus: Dappy]
You lift me off the ground
I always want you around
I ain't gonna let nothing get in the way
I'll never let nothing get in the way (Oh-oh-oh-oh)
You lift me off the ground
I always want you around (Oh)
I ain't gonna let nothing get in the way
I'll never let nothing get in the way (Oh-oh-oh-oh)

[Chorus: Dappy]
Number one
I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)
See, I don't understand how you're number one
When it was just a fling before, now, you're the one
See, all I did was blink twice
From my homie to my only, number one (Oh-oh)

[Post-Chorus: Dappy]
Oh-oh-oh-oh
Oh-oh-oh-oh

Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Oh-oh-oh-oh
Na na nai
