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. "This November's election will determine whether we get to keep moving forward, or if we're forced to go back to policies that ask people like my middle-class family in Ohio to carry the burden -- while people like me, who don't need tax breaks, get extra help," she wrote.
