'90210' preview: Brenda and Kelly feud reignited?

According to reports, die-hard "90210" fans can finally expect to see some hair-pulling between Brenda and Kelly. Maybe. Hopefully. Next week.

And, of course, the feud is still about Dylan. (Luke Perry, however, is not scheduled to return.)

Take a look back at some of television's most memorable catfights.

Here's how E!'s Kristin Dos Santos lays out tonight's episode, which will lay the foundation for next week's potential brawl:

We learn that Brenda has been keeping in close contact with twin brother Brandon and ex-boyfriend Dylan. In this ep, Brenda reveals some heretofore unknown details about Brandon's current whereabouts...But that's not all. Next week, that wayward Dylan finally phones home again. (He could learn a thing or two from E.T.) Apparently the call is to Brenda's phone, but both Brenda and Kelly end up talking to him, and after the fact, the two girls get into a "tense" convo (most likely because he calls Brenda's phone). Eek!
