Oscars 2014: Jennifer Lawrence is the most tweeted-about star

Sally Field, Kim Novak and "Jared Leto's mom" were the most searched terms on Bing throughout the evening, while the red carpet star who triggered the biggest spikes was not a nominee.

Jennifer Lawrence was the most tweeted-about star during the 86th Academy Awards, according to Twitter.

The American Hustle actress likely got an ignominious boost to her social media profile after she took a tumble – for the second consecutive year – while walking the red carpet. Wearing a strapless red peplum Dior Haute Couture dress, she was also considered among the best dressed of the night by THR and others.

Lawrence topped Brad Pitt, best director winner Alfonso Cuaron, best actor winner Matthew McConaughey, best actress Cate Blanchett and best actress nominee Sandra Bullock for most Twitter mentions Sunday night, despite going home empty handed after losing to 12 Years a Slave's Lupita Nyong'o in the best supporting actress category.

During the lengthy televised Oscars show, there were more than 14.7 million tweets worldwide containing terms related to the ceremony. Among movies, Gravity received the most mentions on Twitter during the ceremony, followed by best animated film Frozen, best picture 12 Years a Slave, Dallas Buyers Club and The Wolf of Wall Street.

This year's Oscars also generated the most re-tweeted post ever, as host Ellen Degeneres' selfie -- snapped in the crowd with Brad Pitt, Angelina Jolie, Bradley Cooper, Julia Roberts, Meryl Streep, Kevin Spacey, Jared Leto, Nyong'o and Lawrence -- was shared more than 2 million times, crushing previous record-holder President Barack Obama's tweet after he won the 2012 election (it drew about 780,000 retweets).

Over on Bing, the biggest search spikes were triggered by Sally Field and Kim Novak -- the latter of whom bizarrely presented an award with McConaughey.

Coming in third was Bill Murray's heartfelt shoutout to his late Ghostbusters castmate Harry Ramis, followed by the specific search term "Jared Leto's mom," thanks to Leto's best supporting actor acceptance speech, which eclipsed McConaughey’s on the search engine. Degeneres' star-studded "selfie" and the Wizard of Oz tribute -- specifically, Pink's performance and Whoopi Goldberg's red sparkly shoes -- also provided noteworthy search spikes throughout the evening.

But of all the musical moments throughout the telecast, Bette Midler’s In Memoriam performance of "Wind Beneath My Wings" was the most searched performance of the night, capturing 73 percent of the searches in comparison to the stage spectacles of U2, Pharrell Williams, Idina Menzel and others.

On the red carpet, the most searched star was Charlize Theron, outfitted in a black Dior gown.
