Alicia Keys stars in 'You Don't Know My Name,' which is more like a mini-movie than a music video. The songstress portrays a diner waitress with a dream and a crush on a patron, played by rapper/actor Mos Def. She tries to muster the courage to get him to know her name and imagines a relationship throughout the video, but she never quite "gets there" in real life. This Alicia Keys video is infinitely sad at the end, so you may want to get those tissues ready.
