A block of time on the official convention schedule, between a performance by "American Idol" alum Taylor Hicks and a speech by U.S. Sen. Marco Rubio of Florida, is labled "to be announced."
Names being tossed around the RNC campus have included Sarah Palin, Donald Trump and George W. Bush. But it seems the cat is now out of the bag. Academy Award winning actor-director Clint Eastwood will address the convention tonight. He's expected to walk out on stage for a run-through any moment now.
Eastwood formally endorsed Romney's campaign for president during an event in Idaho earlier this month.
"He just made my day," Romney said. "What a guy."
Other Hollywood celebrities we've seen mingling among the media in support of Romney include actors Jon Voight, whom I interviewed at the 2008 RNC in St. Paul, and Stephen Baldwin.
