Mariah Carey showed off her fun side during an appearance on U.S. show Late Night With Jimmy Fallon on Friday night (01Mar13) by challenging the host in a champagne-related game of beer pong. The pair attempted to bounce ping-pong balls into glasses of Dom Perignon bubbly. Carey won by default when she placed a ball into one of Fallon's glasses and then toasted the Tv host's four-year anniversary.
