Trent Reznor and Atticus Ross won aВ Oscar in the top music categories at the 83rd annual Academy Awards on Sunday (Feb. 27).

Reznor reacted with shock and amazement after he and co-composer Atticus Ross won the Best Original Score Oscar for 'The Social Network' - Reznor's first film score, which also won a Golden Globe.

"Wow. Is this really happening?" Reznor asked during his acceptance speech. "When we finished work on 'The Social Network,' we were very proud of our work and happy to just be involved in this film, and to be standing up here in this company is humbling and flattering beyond words."

Reznor's win was one of three wins for 'The Social Network.' 'The King's Speech' was the big winner with four, taking home the Oscars for best picture, director, actor and original screenplay.
