Summer is officially over, and actress Emmy Rossum is reminiscing about her most memorable lip-lock of the season. So, who is her mystery mate?

A dolphin, naturally.

The actress, 22, blogged about the experience at the Atlantis resort in the Bahamas on her MySpace page. "The dolphin's skin is so smooth and soft," Rossum writes. "They are the sweetest, most intelligent creatures. It was an awesome, albeit a little man-made, experience."

So the question is: Will it last past summer?
