In today's episode of Hollywood Dance Moms, the feud between Deadline's Nikki Finke (Abby Lee, natch) and The Wrap's Sharon Waxman (sucks to be Cathy) goes for another round: this time over Waxman's upcoming annual conference on the intersection of journalism, entertainment, and technology, TheGrill. FX's president is scheduled to speak there, a transgression that has earned his network a coverage ban in Finke's Deadline.com.
