I think I'm pregnant again
I made you believe I wore diaphragms
Oh baby
It might seem like a pudge
But doctors tell me it's more serious
'Cause to be promiscuous
That is just so typically me
Oh baby, baby

(Chorus)
Oops!... I did it again
I opened my legs, got knocked up again
Oh baby, baby
Oops!... You've become a dad
And you're probably mad
I'm not that innocent

You see my problem is this
I'm banging away
Wishing that you were as big as your fist
I like sleeping with gays
Can't you see I'm a whore in so many ways
But to boff all the boy bands
That is just so typically me
Baby, oh

Chorus

"All aboard"
"Britney, before you go, there's something I want you to see"
"Oh, it's so kinky, but wait a minute, isn't this...?"
"Yeah, yes it is"
"But I thought you couldn't be as trampy as me"
"Well baby, I went down on your best friend to prove I could"
"Oh, you shouldn't have"

Oops!... I'm pregnant again with your child
Got stuck with a bastard baby
Oops!... You trusted me (but that's too bad)
I'm not that innocent

Chorus
