"I thought it was a pretty cheap stunt myself. Getting a bunch of celebrities in the background, you're feeding them pizza." U.S. President Barack Obama takes a dig at Oscars host Ellen Degeneres for breaking his record for most retweeted posts on Twitter.com. During the prizegiving earlier this month (02Mar14), the comedienne staged a star-studded 'selfie' at the Oscars with the likes of Brad Pitt, Angelina Jolie, Julia Roberts, Meryl Streep and Jennifer Lawrence. The shot was retweeted more than 3.4 million times.
