EMINEM will be the star performer at next month's Brit Awards.
Organisers have pulled off a huge coup by getting Slim Shady to attend.
But they had to broker a special deal to have him on board.
The MC insisted on a guarantee that he would be a winner on the night - and Brits bosses have said yes.
A source said: "All the stops are being pulled out to make sure this year's ceremony is something to remember.
"Recent bashes have suffered due to an absence of truly legendary figures.
"Eminem is without doubt the biggest star the music industry has produced in the last 15 years. To have him on board is great.
"He didn't want to just perform at the ceremony so he's been assured that he will win something. What that is, organisers haven't worked out yet. But he will receive some silverware."
The rapper will be taking part in the event for the first time in a decade.
But bosses now face a bit of a quandary.
They've axed the Lifetime Achievement gong, which would have been the obvious award for the Grammy-winner. But I'm sure they'll come up with something suitable - which doesn't call the voting mechanism into question.
This year's ceremony is getting the biggest shake-up in the event's history.
The voting academy has had an overhaul, with music industry dinosaurs replaced by artists who will now get to voice their opinions on who they think should win.
