Baldwin bros Alec and Stephen, and Christie Brinkley and hubby Peter Cook perused antique cars while raising bucks to combat breast cancer at the Hamptons Auto Classic in Bridgehampton. The Hamptons Concours d’Elegance featured a lunch to benefit the Carol Baldwin Breast Cancer Research Foundation, a charity very close to the Baldwins’ hearts. Alec, who appeared in a spiked haircut, told The Sheet his new do is for an upcoming flick called The Cooler, about Vegas casinos in the good old days.
