5. Kristen Stewart
She was on the VERY naughty list last year, getting caught cheating on Robert Pattinson with her Snow White and the Huntsman director Rupert Sanders. You'd think the Twilight star would be making a conscious effort to get back in Santa's good books for 2013, but that doesn't seem to be the case. Stewart showed off her extensive vocabulary, shouting obscenities to paparazzi videoing her as she headed to her car a few months back. They WERE asking questions about the Pattinson though, who had been seen planting his lips on another girl. Ouch. Kristen hid behind a gate shouting, 'You're a piece of s*** and you don't deserve to breathe the same air I do.' A LITTLE bit harsh, perhaps Kristen? With Christmas now only a few weeks away, there are rumours the Twilight twosome are back together. When it comes to discussing where the couple would spend the 25th, though, there is huge festive rift amidst the two families. Robert's parents are justifiably weary of Kristen. According to a source in Life and Style magazine - 'They can't stand Kristen; his family is terrified that he'll never get away from her. They think she's bad news. He's supposed to go home to London for Christmas, but Kristen wants him to stay with her in LA - he's torn.' Okay, we actually feel a little bad for Kristen now: no Santa, no boyfriend... someone get this girl three Milk Trays and a bottle of Baileys.
