Marc Jacobs's svelte physique is not the result of his skills in the kitchen. We asked the designer about his cooking repertoire at the Out 100 awards gala on Friday, and it turns out it's, well, fashionably slim. "Cook?" he asked. "I make tuna salad. It's not really cooking, but I chop the spring onions and the celery very, very well, and I put it with tuna fish and mayonnaise and pepper. And that I do extremely well. More than that, I can't do." Marc attended the party on the arm of his on-again-off-again boyfriend, Jason Preston. We asked what Preston contributes, and the Louis Vuitton creative director just guffawed. "Jason? Do you cook?" he asked, turning to Preston who shook his head. "No, he doesn't cook," Jacobs told us, laughing harder. "We eat out a lot, and we have room service a lot." Oh, silly us. We thought Jason was the room service! —Bennett Marcus
