Elisabetta Canalis, George Clooney’s Italian girlfriend, nearly caused a celebrity war because of a misfired Twitter post comparing Jennifer Aniston to punk rocker Iggy Pop. “I just read on Google that I tweeted something bad about J. Aniston,” Canalis posted on her account as way of explanation. “Let me be clear, it’s a complete lie. I would never do that.” Canalis had re-tweeted another user’s catty comparison, saying that Pop looked like Aniston on the cover of Rolling Stone. “I was, at the beginning, not sure what ‘retweeet’ meant,” Canalis explained.
