It costs my heart to say this but Slave 4 U was such a let down

None of the covers are amazing as you guys say they are.

Tonight is the night

I'm sooo excited.

So excited for tomorrow

IKR?

They all...

Truth hurts? :-/

Yes you made a mistake and kept it going even after you were called out.

Yes you first said you're a girl, then a guy, then whatever there is.

So... Report button? Good for you.

I'm not here for the silly quality of livestreams, so Imma wait for the HD ******* to leak.

My poor heart just cannot wait anymore. Even if it's 3 seconds of Britney, I just want to see her on my screen.

OMG GLEE IS TONIGHT!!!!! i told everybody at school. they all knew britney was going to be on it!!

Yes I made a mistake, everybody makes mistakes, no need to be a ------ about it.

Yes I said I'm a girl, then a guy, everyone laughed, the joke ended ages ago, it's not funny anymore & you need to grow up.

Glad you enjoyed the warning.

when someone DVR's the show does it count as a view? i know A LOT of people who are doing that.
