Guests at a gala in Gstaad for the Alzheimer’s Society thought charity ambassador Carey Mulligan was overcome when she gave a speech. But, the star explained, she’d stepped out to take a call from husband Marcus Mumford, then had to rush to grab the mike after Harvey Weinstein spontaneously donated $5,000 of the evening’s $70,000 haul. “I’m not emotional, I’m just out of breath. I’ve been running!” she said at the event, part of aSmallWorld’s Winter Weekend at the Palace Hotel.
