General Wesley Clark’s relationship with a New York woman less than half his age, Shauna Mei, hasn’t exactly been kept a secret from neighbors in her Noho apartment building. After Page Six exclusively revealed yesterday that the retired 68-year-old US Army general and former NATO Supreme Allied Commander is dating 30-year-old Mei, the founder of online retailer AHAlife.com, one source told us, “He has been spotted numerous times in her building at 45 Bond Street, going into her apartment or going out with Shauna. Despite the age difference, they make a very handsome couple.” Clark was married to Gertrude Kingston Clark for 45 years before filing for divorce last year.
