Who doesn't love karaoke? While you might be a little too shy to sing your guts out in public, actors generally aren't. I love hearing stars belting out music in movies, but I'm not talking about polished musicals — I'm talking about funny, sometimes embarrassing, and sometimes surprisingly perfect singing in movies. If you can't hear the song "Pocketful of Sunshine" without thinking of Emma Stone, or if the Cups song became your favorite jam after Pitch Perfect, then you'll get a kick out of this slideshow.
