Hilary Duff vs. Avril Lavigne

The Feud continues between Pop tarts Hilary Duff and Avril Lavigne.

Hilary and Avril were at the same party in New York last week, but they had to be kept far, far apart from each other because of a long-running bitchfight between the two, says insiders.



The two pop starlets were supposed to come at different times, but arrived at the exact same time, and Avril was "driving everyone crazy" with her anger.

God I love a good cat fight - and this one spikes high on the sexy-o-meter.
