Name of video , who's in it??

Hi, I'm looking for a video that I saw years ago (could be 1 year, could be like 5 years). I don't actually know the name of the video OR the names of anyone in it. I DO however remember the general plotline of the video.
It has to do with catching his girlfriend cheating on him.

Guys hanging out with his buddies at one of their houses. His girlfriend comes over (he hides) and she goes swimming (While she's changing they try and film her changing and she gets all mad). When shes outside swimming she starts making out with one of the guys and then they start going at it. This whole time she's being "secretly filmed from inside". Eventually the camera man sneaks outside and films them from closer, and then she gets confronted and storms out.

Thats all I got, hopefully someone can let me know what its called, or the name of the girl. Thanks!
