Speculation is rising that late night talk powerhouse Larry King will be hanging up his 'Live' mic when his current contract with CNN expires in 18 months. If he does retire, which King himself has revealed little interest in doing, there is no shortage of potential successors waiting in the wings.

Rumored contenders to take Larry's chair include 'American Idol' host Ryan Seacrest, network anchors Diane Sawyer and Katie Couric, CNN correspondent John King and co-host of 'The View', Joy Behar.

Each of the potential replacements has a complication, according to a report by the New York Post.
