(January 5, 2012) -- During his off time at the 2013 Hyundai Hopman Cup, Tommy Haas spent some quality time with Karen the Koala, which leads us to the obvious question: Who is cuter, Haas, with his movie star good looks, chiseled features and flowing hair, or Karen, with her adorable fuzziness, red-eyed plaintive stare and capacity for cuddling? We're going with Karen. There's just something about her. But Haas is no slouch either.
