Bo Jackson chatting today

We have a real celebrity taking over ESPN's chat today.

Former Auburn great Bo Jackson will be live to answer all your questions at 4 p.m. ET. The Heisman-winning running back will stop by to talk about being a two-sport star, as well as his charity work.

From April 24-28, Jackson will ride 300 miles across the state of Alabama in his Bo Bikes Bama ride to raise money for the Governor's Emergency Relief Fund to help the victims of the state's deadly tornado outbreak in 2011. Jackson hopes to raise $1 million for his ride.

This might be showing my (young) age, but I once did a report on Jackson when I was in elementary school. And yes, I did get an A.

Stop by and chat it up with one of the SEC's best this afternoon, whether you're an Auburn fan or otherwise.
