Oscars host Ellen Degeneres shut down Twitter.com on Sunday (02Mar14) after gathering stars including Brad Pitt, Angelina Jolie and Julia Roberts for an all-star selfie in a bid to set a new world record for the most re-tweeted photo. Meryl Streep, Jared Leto, Lupita Nyong'o, Jennifer Lawrence, Kevin Spacey, Channing Tatum and Bradley Cooper, who took the snap, all squeezed into view for the shot, which the comedienne posted on her micro-blogging profile. The accompanying caption read: "If only Bradley's arm was longer. Best photo ever." She then encouraged everyone in the audience at the Dolby Theatre in Los Angeles to re-post the image, and the snap quickly racked up more than 500,000 re-tweets and 300,000 'favourites' within minutes. The heavy website traffic caused Twitter to temporarily break down, but as WENN went to press, the photo had garnered around 2.2 million re-tweets and had been 'favourited' almost one million times.
