[Verse 1:]
I'm sure that you heard the rumors 'bout me
Word on the street is I'm that 'B'
But you didn't care nothing 'bout that
Said I was the one you had to have
Knowing that I wasn't into no games
Wasn't tryna' take nobody's last name
But you changed my mind
Took me off the grind
Now I'm yours for life.

[Pre-Chorus:]
What if I never met you?
What would it take to get to
This thing that you do,
That can't nobody else do
What if you we're still on the block?
Would this love we got make you stop?
I don't wanna ever think about it
Can't do without it.

[Chorus:]
Who Knew?
It would be you changing my plans,
Stealing my heart
Who knew?
You were the one just like me
Snatch a sista up and wifed me
Who knew that you would be my baby daddy?
Spending all your hard-earned money on me
You came out the blue, boy I'm glad it's you
Tell me who knew?

[Verse 2:]
Ain't nobody gonna take me
'Cause you're the only one that ever shown me
What it's like to know real love
What it's like to get that good love
Getting turned on and getting turned out
Getting it so good that there's no doubt
There ain't never gonna be a time
When I'm not his and he ain't mine

[Pre-Chorus]

[Chorus]

[Bridge:]
It coulda' been you with some other chick
And it coulda' been me with another man
You could've walked by and none of this would happen
Now we're shopping for baby shoes
Now it's rings, bells, and a preacher too
Now we're forever
Tell me who knew?

[Chorus x2]
