You can watch the Oscars live and go backstage for exclusive content here: http://oscar.go.com/the-oscars-backstage or through a free App available called Watch ABC -- exciting! Have a great Oscar Sunday, and best of luck to Cate Blanchett (nominated for Best Actress) and all the other outstanding Oscar nominees!
An update -- some folks have had problems with the Watch ABC App. A good alternative is the IMDB App. Visit IMDB.com and click on Apps and select your version depending on which phone or device you are using. It's free and an excellent App!
