Separation has had a strange effect on David Arquette. The actor, who split with Courteney Cox in October, was spotted looking a little wobbly and wearing a circus outfit in Miami Beach on Wednesday night. Accompanied by midgets and his pal and business partner Jeff Beacher, Arquette hit club Liv at the Fontainebleau, as well as a party thrown by millionaire Miami man about town Wayne Boich. A source told us, “Arquette came to the party dressed as a clown. People thought he was the hired entertainment until he started hitting on their girlfriends.” A rep for Arquette said: “He was in a tux and tails not a clown and he said he didn’t hit on anyone.”
