My Take On The Poem:

Y'all keep shouting, "Gimme, gimme, gimme more,"
But little do ya know, some surprises are in store.
[We keep asking for more news/info about Britney, and now we are finally about to get some info the surprises Britney has up her sleeves.]

No matter how many gallons of Celebrity Juice you drink,
There's more around the corner, so much more than you think.
[Personally, I believe this is referring to an article Perez Hilton posted on his site. "Celebrity Juice" is referring to Perez's logo on the top of his site. He posted a supposedly 'confirmed' tracklist and info about The Singles Collection, but he later took it down after finding out it was fake. Britannica is saying that there's a lot more than what he posted.]

So please quit breathing heavy, I hate to hear you sigh,
I know I drive you crazy... oops! I did it again, didn't I?
[This obviously is referring to Breatheheavy.com where the same article that Perez posted was originally created. It was created only has an imagined idea of The Singles Collection, but a lot of people were confused by it (including Perez) and believed it to be the real deal. Then, the part about driving us crazy is just cause she knows all the suspense around this will drive us fans nuts!]

As much as I lov3 contests, that isn't what this is about,
I'll tell you soon enough, 'cause I hate seeing B fans pout.
