Mystery solved. Or maybe not. The "mystery guest" who will take the stage just prior to Mitt Romney's introduction tonight will be actor, former Mayor of Carmel, CA, and unabashed Hollywood Republican Clint Eastwood, according to Fox News who heard it from one anonymous source.
Sounds a little shaky to me. With no one confirmed yet, speculation is still running wild.
Officials confirmed Wednesday that a surprise guest was still on the schedule but declined further comment.
One Republican source told FoxNews.com that Eastwood is indeed the mystery speaker, following an online report that claimed the actor is planning to travel to Tampa for the convention.
If the Academy Award winner is the one, he could get a mixed reception with the Hollywood-leery crowd.
"He's all right, despite being associated with Hollywood," Bruce Thompson, a California delegate, said laconically. "He's a good guy and was a good mayor."
The chatter comes shortly after Eastwood endorsed Romney for president, despite cutting a Super Bowl ad earlier in the year that some saw as a subtle push for a second Obama term..
New York Jets quarterback Tim Tebow, a new face of Christian conservativism, is another name being bandied about as the possible speaker.
Rachel Ayers, a senior at High Point University in North Carolina who was touring the convention center Wednesday morning, lighted up at the mention of Tebow.
"Tim Tebow would be amazing," said Ayers, who with several others also wanted to see a former Bush president or first lady.
Her classmate, 19-year-old Kyle Berube, put his odds on Palin, the former Alaska governor and 2008 GOP vice presidential candidate.
The cancelation of Monday's events because of then-approaching Tropical Storm Isaac took some star power away from the convention because A-list speakers such as Louisiana GOP Gov. Bobby Jindal had to cancel to focus on potential storm problems at home.
Asked about who might be able to give the crowd a surprise on Tuesday, Matt Kenney, a staffer for Senate Minority Leader Mitch McConnell, said playfully: "Maybe a Ronald Reagan hologram."
Eastwood would be good, Tebow better, and Nancy Reagan best. Whether it's one of them or someone totally off the wall, we'll just have to wait and see.
