Social media is abuzz with jokes on Jennifer Lawrence 'repeating' her fall once again at the Oscars. The actress tripped on the Red Carpet this year much to everyone's amusement. 'Sherlock' star Benedict Cumberbatch photobombed U2's group picture making the regular picture look rather interesting. But the best moment came when host Ellen Degeneres took a group selfie with almost all the stars in it. Degeneres was also seen distributing pizza slices to stars sitting in the audience and Brad Pitt came to her assistance and started distributing plates to his friends in the audience.
