Jay-Z and Diddy may just have to watch history from a distance. According to Chicago Sun-Times columnist Bill Zwecker, Hov, Puff and Mary J. Blige have been strongly advised to miss Democratic Presidential Nominee Barack Obama's rally in Chicago's Grant Park tonight (11/04). Word is the aforementioned celebs had been trying to get their hands on VIP invites to attend the event. Instead, the stars were told to think about attending a possible Obama inauguration in January.

''There really only needs to be one star in Grant Park, and that's Barack,'' an Obama insider told Zwecker."There will be plenty of time for a new President Obama to be surrounded by famous fans, all hopeful about a new administration.''

Actors Tim Robbins, Susan Surandon and Ben Affleck were also among the celebrities advised to keep a distance. Longtime Obama supporter Oprah Winfrey is the only celebrity expected to make an appearance at the rally tonight.

Diddy and Hov have been quite vocal in their support of Obama through the Illinois Senator's campaign. Jigga recently held a rally alongside Cleveland Cavalier Lebron James and joined Diddy and others in Florida rallies just two days ago. -Marvin Brandon
