Madonna is going to use her star power to help boost her husband Guy Ritchie's new movie "Revolver."
Madge and her director spouse are set to co-host a VIP preview of 'Revolver' this coming Sunday. Her guest list already includes Howard Stern, Lauren Bacall, Helena Christensen, Patricia Clarkson and Ivanka Trump, among others.
A source said: "Madonna is planning to sprinkle a little stardust on Guy's latest gangster film."
'Revolver' is due in US theaters on December 7.
