Nelson Mandela's 90th birthday bash isn't until Friday, but celebs are already flocking to London to fete the former South African president.
Will Smith (who's emceeing Friday's event) and Jada Pinkett Smith were just two boldfaced names in attendance at a prebirthday dinner party held in Hyde Park. Also on the list: Oprah Winfrey, Uma Thurman, Forest Whitaker, Kim Cattrall and Denzel Washington.
And yes, Naomi Campbell will be in the house on Friday.
Despite reports that the birthday boy had banned the supermodel from introducing some of the performers after her airport arrest, her rep says that was never the plan.
"To my knowledge, she has always just been a guest," he told E! News.
One trainwreck who is allowed on stage at the soiree? Amy Winehouse. The troubled singer is slated to sing, as well as Leona Lewis, Queen and Annie Lennox.
It will be Amy's first performance since her hospitalization last week.
