you mean, carla CORIA?? did she said that too?
I guess GG means when Carla answered "his back" in the Tenis Pro show in Acapulco last year (with Calleri's and Chela's wives, when they were asked which body part of their husbands they prefer).
As for him looking like a cat, there often are/were cartoons about the players during the matches on French TV and the cartoonists (who obviously don't have much clue of tennis) always represent Guille as a cat, they will never get that El Gato = Gaudio.
And I agree with GG, he looks skinnier to me in these pics. At least he didn't put on weight during his never-ending holiday.
