Perhaps feeling the heat of his cheating scandal, Kanye West jet to Switzerland Wednesday -- without pregnant girlfriend Kim Kardashian -- for a surprise show at the Art Basel show currently running there.

The New York Post reports that the Heartless singer was slated to perform at the brand-new Herzog & de Meuron exhibition hall for the swanky festival, which is showcasing more than $2 billion worth of art. Other notable names for the highfalutin exhibition include Leonardo DiCaprio, and Peter Brant, the billionaire hubby of supermodel Stephanie Seymour.
