An eyewitness tells ET the couple was smiling and laughing together, and showing more PDA than usual during their romantic Manhattan stroll.

"Kelly was dancing a little bit and Leo was laughing with her," says the eyewitness, who adds that the two also hugged. "Most of the time the two held hands, and Leo adoringly smiled at Kelly a lot."

Despite having modeled for less than two-years, Kelly was named Sports Illustrated's Rookie of the Year in March, and posted this revealing underboob pic in June from her shoot with the magazine.
