Although I have never said it personally myself, I htink some of you are starting to get the same impression I got about Lopez.
I spent an hour trying to find any evidence that he has ever even been on a cruise ship - and i can't find any. I know he did a press party in New York City, along with Guy Fieri, and at that event he said he was going to take his first criuse later in 2012, but I can't find a single picture or new release that he ever did it.
So - my guess is that they have a loose connection if any at all. His given title was "director of comedy" for Carnival, but on the CCL web site they are advertising to hire a director of comedy.
That job description says "must work with the GLopez company in helping select talent" - but on its own that is a meaningless statement. To do what?
