Heidi Klum may have a collection of New Balance sneakers, but she had trouble keeping her balance at a party celebrating her Hamptons magazine cover on the STK rooftop Wednesday night. The “Project Runway” star “accidentally tripped over her 6-inch heels and spilled her glass of water over the man who caught her,” a source said, adding, “he then took his soaked shirt off, showing off his muscles, to her delight.”

Klum, who runs four miles a day, was later seen sipping a beer, and when guests asked why, she replied that beer is “healthier for runners” than other forms of booze.
