ET breaks the news that Sean "Diddy" Combs will make a two-episode guest appearance on "CSI Miami." The mogul will be playing a federal prosecutor who has a conflict with Horatio (David Caruso) and his team not only on a case, but also in their personal lives.

Look for Combs' episodes to air in early 2009.

Combs' last outing as an actor was on the Emmy-nominated "Raisin in the Sun."
