If I Knew lyrics by Bruno Mars.

Oh Oh Oh I was a city boy
Right into danger's where i'd always run, a boy who had his fun
I wouldn't have done
All the things that I've done
If I knew one day you'd come

Now baby, now baby, now baby, now baby
Oh, oh I, I know it breaks your heart
To picture the only you wanna love
In someone else's arms
But I wouldn't have done
All the things that I've done
If I knew one day you would come

Now baby, now baby, now baby
Ohh baby please
Lets leave the past behind us
So that we can go where love will find us
Yeah will find us

I know once girls would leave me
But I know that you believe me

Baby I, I I wish we were seventeen
So I could give you all the innocence
That you give to me
No, I wouldnt have done
All the things that I've done
If I knew one day you'd come
If I knew one day you'd come
