(Newsroom America) -- Chatter increased Thursday at the Republican National Convention in Tampa, Fla., over the identity of a supposed "mystery guest" who is scheduled to show up on the final evening of the event, as the party's presidential nominee, Mitt Romney, prepares to deliver his acceptance speech.
Reports said that convention officials have confirmed that such a guest is scheduled to appear, but they declined to disclose his or her identity. Some of the names being reported include Hollywood great Clint Eastwood, GOP activist Sarah Palin and talk show king Rush Limbaugh.
Fox News reported that a Republican official told the news service that Eastwood is the guest in question. Eastwood, a libertarian-leaning former mayor of Carmel, Calif., has already endorsed Romney for the presidency.
New York Jets quarterback Tim Tebow is also being mentioned as a possibility.
