WHAAAAAAAAAAAAT!!!!!!!!!!!!!!

OMFG I KNEW IT!!!!!! I SWEAR I DIDDD, YAASSS, IF IT IS TRUE, THEN TO BRITNEY'S TEAM!!!!

Rihanna? Please be Rihanna.

I'd rather it be on Britney's next single. TTWE isn't the right one, IMO.

Rihanna is returning the favor #TeamR&B

HOLY ****! This better be fake

It's Hilary Duff y'all

I'd rather Nicki Minaj or Ke$ha.... just so it doesn't seem to static. I want Britney to branch out more and more.

Nicki Minaj. There's no other option.

"this better be fake"? SERIOUSLY?

WHY? cause you can't handle some competition? ugh, you guys, seriously, haven't even heard it and are already complaining

this was MEANT to happen, the most probable thing is when S&M stops being a threat to a new peak for TTWE, they release the remix with the feature...

everyone thinks it's Rihanna... my money's on Ke$ha

OH MY GOOOOOD! THAT'D BE WAY TOO EPIC Hope it's true!

If K$ is on this . . . I wouldn't mind hearing her more on the radio, though.

nooo IT HAS TO BE RIHANNNA............. i dont think Jive or her manager would be dumb enough to let Britney did the S&M rihmix for free. there must be a return in favor

probably Ke$ha

It's Jennifer Lopez ...what if Gaga?

I think Nicki is the clear choice...perfect cross promotion

This! I much rather it be for a 3rd single though.
