wikipedia says that Special guest stars:

Usher - OMG
James Corden & Dizzee Rascal- Shout for England [16]
Lady GaGa - Alejandro

has this been confirmed?

GaGa was pictured earlier today at Heathrow Airport, so I doubt she'll be there - she's probably on a plane back to America as we speak!

Unless she just popped to Duty Free lol.

i know its dizzee and cordon not sure about the others.

Sick of the sight of gaga

I'm sure I read somewhere that Susan Boyle's on tonight?

Same here

Well Usher is, according to my Sky guide.

I think GaGa has left the country.

& the other two.. Dear God, I hope not.

That'll be me turning off, then.

GaGa, 8 hours ago on twitter

The Mirror says Dizzee & Corden are performing it.

Easily the worst acts ever to grace the stage, if indeed it is true.

Dizzee rascal AND C orden? Oh dear
Plus why would they bring up England specifically, when all of Britain is watching it?

Usher, Dizzee/James corden have been confirmed by Tony Cowell on twitter.

Fern Cotton mentioned Dizzee and Corden were on tonight because Simon Cowell was involved in making the song.

i like OMG

Well, Simon Cowell is behind the song.

It's released on Wednesday.

Kerching.

All profits go to Great Ormond Street hospital

I really wanted gaga to sing tonight oh well
