Who is this guy celeb from Argentina?

You have got to be kidding? You really saw him while in Miami? Probably the most popular show in Argentina right now is a show called "Este es el show". There's a host and 5 judges of dancing couples. Ricardo Forte (not Enrique) is one of the judges. There was supposedly a big fallout between the show's host and Forte and Forte ran off to Miami for a little while and the cameras followed him there. Now he's back on the show. Now that you have his correct name, you should not have any problem googling him.
