Duff and Lavigne continue public feud

Hilary Duff and Avril Lavigne have continued their public feud, according to sources.

The pair attended the Maxim Hot 100 party this week, and deliberately scheduled their arrival times to avoid each other. However, by coincidence the two arrived at almost identical times, leading to mutual unhappiness.

Witnesses at the party claim the pair spent the evening bitching about each other, and continuously threatened to leave the event unless the other went home.

Sources noticed a "definite tension" throughout the night, and one added that Lavigne was so angry that her behaviour was "driving everyone crazy."
