Twitter is abuzz over President Barack Obama's Nobel Peace Prize, which was surprisingly awarded to him early Friday morning, taking three out out of ten trending topics on the microblogging service. 

Trending topics allow users to track the most popular conversations among tweeters. "President Obama" is the second most popular topic,  "Barack Obama Wins" is the seventh most popular topic, and "Nobel Peace Prize" is eighth. 

The Nobel Committee announced early Friday morning it was honoring Obama for his “extraordinary efforts to strengthen international diplomacy and cooperation between peoples.”

Presidents Theodore Roosevelt and Woodrow Wilson are the other two sitting presidents who were awarded the prize. 

The president is expected to make a statement on the award today.
