The song is gorgeous, finding the bi-curious pop tart at a more emotional place than radio has discovered. When he's shipped off to World War II, Katy misses her man (played by Kyle XY and "Goodbye My Lover" hottie Matt Dallas) and ends up in bed with another. She reminisces, which allows her 32Ds to fill out some lovely vintage costumes, before revealing the real reason she can't be with him. Her range as an actress is only decent, and the makeup at the end looks a little whorish, but all-in-all a welcome departure that will cement Katy Perry as a pop star with some staying power. Watch:
PS: This is the second video for "Thinking Of You" The first was filmed before "Hot N Cold" was released as a single. It's rather violent and seedy (which is probably why it was scrapped) you can watch it here.
