Is Britney going to perform on the Grammy's?

Britney is set to open the 52nd annual Grammy awards. This was edited to her wikipedia-page which is protected. So this message is probably from Britney's team. But Britney and her team haven't react yet. So this is probably just a rumor. Yesterday her choreographer tweeted: "hey B are you going to perform on the grammy's? There are only 5 weeks left! I hope you do but hurry!"
Is this a hint?
Well if she is going to open the Grammy's she will perform her new single 'Hold It Agains Me' which will premier this Tuesday! (1/11/11)
So, plenty stuff to talk about! Thoughts? I wold like to hear them! I hope she will perform!!
