As he unveiled the nightmarish collage on Late Night With Conan O'Brien, the host remarked, "If they had a child, what would it look like? It's like a maitre d' at a restaurant I ate at."

The unlikely twosome were said to have been spotted at an "intimate meeting" at Los Angeles' Whiskey Bar, sparking rumours they are Hollywood's newest couple.
