...as are Ryan Seacrest, Ty Pennington, Keidi Klum, Jeff Probst and any other reality host/hostess!
As of this Fall's Emmy Awards, there is a category for "Outstanding Host for a Reality or Reality-Competition Program". The hosting distinction is important because this eliminates someone such as Simon Cowell from being eligible. According to the TV Academy only a "proactive master of ceremony host[s]" is eligible - if the person is solely a judge they are not.
So...who do you think is the most notable host/hostess of a reality competition and is most deserving of an Emmy nomination??
