You say we did it
And I'm the dad
My lawyer's trippin'
Cuz this looks bad
You only said this
To get my cash
And now selena gomez is going to kick my ass

It's not my baby, baby, baby
Nooooooo
It's not my baby, baby, baby
Nooooooo
It's not my baby, baby, baby
Nooooooo
I'm telling you it's not mine

Now there's a lawsuit
Girl quit playin'
Paternity test
Are you insane?
Girl please stop talking
Just let this go

I'll buy you anything
I'll buy you any ring
You said I didn't use protection
I only lasted 30 seconds
But that's not true
No, that's a lie
It was totally more like 45

It's not my baby, baby, baby

Nooooooo
It's not my baby, baby, baby
Nooooooo
It's not my baby, baby, baby
Nooooooo
I'm telling you it's not mine

Rap
When I was sixteen
I had my first sex
It was backstage at my concert
In a bathroom I saw my first breast
She was my first lover
Gotta that bathroom sink
I forgot to put a rubber
On my shrinky dink

Gotta use some t & a
The misionary in the lavatory
So she wants my dna
And now I gotta go on to my the show
She had me feeling happy
But now I'm feeling crappy
Her claims I did not flatly
I ain't that baby's daddy

Baby, baby, baby
Nooooooo
It's not my baby, baby, baby
Nooooooo
It's not my baby, baby, baby
Nooooooo
I'm telling you it's not mine
