Serena Williams' dog, Chip, travels with her, and her hotel in Rome—she's currently there for a tennis match—offers a special room service menu for dogs. The food she ordered for Chip looked really good one day, so the next day, she ordered him salmon and rice and decided to taste it, E! reports. "I ate a spoonful," she admitted in a Snapchat video Wednesday. "Don't judge me, I ate a spoonful." It did not end well: "Let's fast forward two hours. I just ran to the toilet like ... I thought I was gonna pass out." She admits that even though the food looked good, "It did taste weird. I force-swallowed it. ... I don't think it's consumable for humans."
