Here's the remix with Britney Spears doing a verse:

Lyics:
Feels so good being bad (Oh oh oh oh oh)
There's no way I'm turning back
Now the pain is my pleasure cause nothing could measure

Love is great, love is fine
Outta box, outta line
The affliction of the feeling leaves me wanting more (Oh oh oh oh oh)

Cause I may be bad, but I'm perfectly good at it
Sex in the air, I don't care, I love the smell of it
Sticks and stones may break my bones
But chains and whips excite me

Cause I may be bad, but I'm perfectly good at it
Sex in the air, I don't care, I love the smell of it
Sticks and stones may break my bones
But chains and whips excite me

Na na na na
Come on, come on, come on
I like it-like it
