The latest Aerosmith singer rumour is...Sammy Hagar!  Classic Rock cited an "unnamed source" saying that Hagar was the latest in a line of possible replacements including Billy Idol, Chris Cornell and Paul Rodgers.  Hagar's manager says this is not the case.  "Good authority must mean The Enquirer because his Led Zep gig conflicts with the Aerosmith job.... Seriously, Sam is very happy to be going into the studio with Chickenfoot to start the second album in April."  Chickenfoot is working on a new album right now - read an interview with Joe Satriani about the project here.
