A party this star-studded would normally be reserved for Oscar night - unless it's a fete thrown by Madonna! The Queen of Pop hosted a Gucci party in New York City last night, which also served as a fundraiser for her Raising Malawi foundation and UNICEF. Joining her Madgesty were a slew of A-listers in their designer best, including Tom Cruise and Katie Holmes, Jennifer Lopez and Marc Anthony, Demi Moore and Ashton Kutcher, Gwyneth Paltrow, Salma Hayek and Drew Barrymore with her beau, Justin Long. Performing for the celebs was R&B princess Rihanna. Madonna sure knows how to throw a party!
