Not only was Ellen Degeneres a pretty awesome Oscar hostess, she managed to break Twitter records at the same time. Her Oscar selfie with Bradley Cooper, Jennifer Lawrence, and several other celebrities went viral on Twitter, racking up more than 700,000 retweets in 30 minutes and temporarily crashing the social-networking site. As of Monday afternoon, her tweet has nearly 2.7 million retweets. The previous record for most retweeted went to a photo President Obama after he won his second term in 2012, which got 778,000 retweets. The Twitter honor doesn't just go to Ellen, but Samsung, which was the maker of the smartphone that tweeted the selfie. Clearly, Samsung's Oscar sponsorship more than paid for itself.
