Watch Jennifer Hudson Kill It at the 2013 Oscars

Since the "theme" for the 2013 Academy Awards is music in movies, it makes sense that Oscar-winner Jennifer Hudson would be called upon to perform the big number from the movie that won her the prize, 'Dreamgirls.' Here she is singing a bit of 'And I'm Telling You.' This number followed a pretty jazzed-up bit by Catherine Zeta Jones in a musical medley from 'Chicago.' What do you think of Hudson's performance?
