You sang you butt off. Look how much lipstick you've got on the microphone!

Christina [Aguilera] sang her butt off -

I sing a lot, so if I have lipstick, it gets all over the microphone, so I rarely wear lipstick.

You made it fun and you made it your own,

Lips are the outward sign, the emblem of desire, and lipstick is the ink in which we graffiti that message on our smile, our pout and pucker. When a girl blows a man a kiss she is sending him a piece of her soul.

Better red than dead. Not sure what that means, but I say it in my head every time I put lipstick on.
