You say that I'm messing with your head
(Yeah yeah, yeah yeah)
All cause I was making out with your friend
(Yeah yeah, yeah yeah)
Love hurts whether it's right or wrong
(Yeah yeah, yeah yeah)
I can't stop cause I'm having too much fun
(Yeah yeah, yeah yeah)

You're on your knees, begging please, 'Stay with me'
But honestly? I just need to be a little crazy

All my life I've been good, but now?
I, I, I, am thinking what the hell
All I want is to mess around
And I, I, I don't really care about

If you love me, if you hate me
You can save me baby, baby
All my life I've been good, but now?
What the hell

What? What? What?
What the hell

So what if I go out on a million dates?
(Yeah yeah, yeah yeah)
You never call or listen to me anyway
(Yeah yeah, yeah yeah)
I'd rather rage than sit around and wait all day
(Yeah yeah, yeah yeah)
Don't get me wrong, I just need some time to play
(E-yeah-ay)

You're on your knees, begging please, 'Stay with me'(la la la-ah)
But honestly? I just need to be a little crazy(crazy)

All my life I've been good, but now?
I, I, I, am thinking what the hell
All I want is to mess around
And I, I, I don't really care about

If you love me, if you hate me
You can save me baby, baby
All my life I've been good, but now?
What the hell

When I'm messing with you in bed

All my life I've been good, but now?
