Kenneth Cole made a “Baywatch”-style rescue of a man who fell into the pool at Hotel Americano on Thursday night. Cole and staff from his company gathered at the Chelsea hotel after his Fashion Week runway show nearby. But as the gang celebrated, one of Cole’s male employees fell into the 4-foot-deep, narrow pool. “K.C. just extended his hand and got him out, and then they hugged,” a spy told us. Then the designer handed the guy a beer, and the party went on. Cole’s show was his first after a seven-year hiatus from the runway, and hosted Brooke Shields, Heidi Klum, Armie Hammer, model Alyssa Miller and Cuba Gooding Jr. in the front row.
