You might think this is Anne Hathaway in the middle of threesome. I only know she was, and maybe still is, a girlfriend of actor Brian Geraghty, who had one of three key roles in a famous film by Kathryn Bigelow "The Hurt Locker". Brian is on her left side. Party was on the sea float. (I found out her name - Krysten Ritter; she's actress, too).
