2. Kristen Stewart  

Seems vampires aren't the only immortal beings. The Kristen Stewart/Robert Pattinson saga simply refuses to be buried. The Twilight couple has been in a steady cycle of break-ups and make-ups since the young starlet confessed to cheating on RPatz in July 2012. The other man in the picture – Rupert Sanders, who directed Stewart in Snow White and the Huntsman – was a married father of two at the time.{relatedarticles} Paparazzi images of Stewart and Sanders showed the pair kissing and canoodling in a parking lot. Other snaps showed them getting hands-on on a hiking trail, where Stewart was pictured holding Pattinson's baseball hat. Sources have said the infidelity is a continued source of contention for Stewart and Pattinson, who have reunited and split several times since the revelation. As for Sanders, his stunning wife, model-actress Liberty Ross, left him in the dust.
