Larry King, Ryan Seacrest -- Radio Silence

Larry King and Ryan Seacrest have been secretly plotting to relaunch Larry's radio career ... TMZ has learned.

Sources tell TMZ ... Ryan is talking to Larry about producing/distributing a new Larry King syndicated radio show, as part of a mega-media deal Seacrest is creating.  BTW, that's how Larry became famous -- radio.

Ryan, whose radio deal with Clear Channel is up in November, has been around town talking to big wigs about creating a multi-media empire, including TV and the Internet. 

Ryan was at dinner last night with DreamWorks Animation Chief Jeffrey Katzenberg -- and we're told they were discussing the plan.

Those damn rich people ...
