Anne Hathaway stars as the victim in this scene from The Princess Diaries (2001) as her friends leave her embarrassed and exposed on the beach.
In the movie Pretty Cool Too (2007) a geek gets hold of a magic cell phone which has mind control powers. In this scene, after accidentally walking in on a busty blonde taking a bath (who is very embarrassed and shouts at him) he quickly convinces her he isn’t actually in the room at all. So she proceeds to dry herself while he watches, unaware he is still there drooling over her massive tits and checking our her ass and pussy!
This is a short but sweet clip from La petite amie (1988). Hot girl Agnès Blanchot walks out of a hotel bathroom wearing only her Walkman, which explains why she didn’t hear eight people walk into the room. She gets a rather embarrassing surprise, gasps and scurries back into the bathroom as everyone else laughs at her predicament.
