The "Sex and the City" star will pass the hat among her well-heeled friends and colleagues on June 14.
The Hill said Parker spread the word by e-mail, promising a "fabulous" event and announcing a raffle for fans who can donate $3 or more for a chance to win a spot on the guest list plus travel costs and tickets to a Mariah Carey concert.
The glitzy event follows the same basic formula as the recent Los Angeles fundraiser at George Clooney's place, which pumped about $15 million to the president's re-election campaign.
Parker noted in her e-mail that while the party will be definitely A-list, she has the working stiffs in her heart.
