Literally: There's a rally for the Democratic White House hopeful going on at the Dorothy Chandler Pavilion, and it's packed with Hollywood bigwigs.

Don Cheadle and Dennis Quaid have already spoken, and Seal performed while accompanied on piano by megaproducer David Foster.

Also in attendance are Samuel L. Jackson, Kerry Washington, Leonard Nimoy, will.i.am, Lisa Ling, Zooey Deschanel, indie rock band Death Cab for Cutie, producer Lawrence Bender, studio honcho Sherry Lansing and what one rally-goer describes as "the entire Kennedy clan."

A source says Obama is about to hit the stage himself and is surrounded by a "s–tload of Secret Service. Wow!"

Wow, indeed.
