In keeping with this year's Oscar tribute to movie musicals, Jennifer Hudson performed her rendition of "And I Am Telling You I'm Not Going" from the movie that earned her an Oscar, Dreamgirls. It goes without saying that she's fantastically talented, but I think her performance on Oscar night may have been the best I've ever seen of her. Watch the clip here (and see the GIF!), and you can also watch the full Oscar show online for the first time at ABC.com, the ABC player for iOS, and Hulu Plus.
