In news to me, Avril Lavigne and The Duffs are embroiled in a bitter feud which spilled over to the Maxim Hot 100 party. Despite their handlers making every effort to keep them apart at the event, the two arrived at the same time and created a “tension” as Avril threatened to leave and drove everyone crazy. So actually only Avril was causing the tension. The Duffs were too busy munching on carrots and oats to care. They have such beautiful manes.
