WIREIMAGE The world will find out soon enough just what kind of friends Madonna and Alex Rodriquez are if the Material Girl arrives (as planned) at a party hosted by the New York Yankees slugger on Monday, July 14. "Alex is having a party for the 2008 Major League All-Star game in New York," a source close to him tells Life & Style. "It's at the 40/40 club in NYC, and Madonna has RSVP'd to attend!" While a rep for Madonna denies the RSVP, the source adds "Madonna knows about the party and has said she is coming. Alex's name, of course, will be on the top of the invite, but Madonna's name will be on it, too, as a confirmed 'guest,'" the insider adds. "He'll be first on the list, it's his party. But she'll be right there, too." There's no word on whether Madge's husband, Guy Ritchie, will be joining his wife at the fete.
