The Jackson brothers play L.A.'s Greek Theatre this weekend as part of their "Unity" reunion tour. But don't expect to see niece Paris Jackson showing up for the gig, unless Michael's daughter is there to picket.

The name of the Jacksons' tour seems ironic — to say the least — in light of the enormous family feud that's coming to light, with 14-year-old Paris and her 82-year-old grandmother Katherine forming an intergenerational alliance on one side, pitted against her uncles and aunt Janet on the other. The most serious issue is a dispute over Michael Jackson's will, although Paris's acting aspirations and a stroke that Katherine may or may not have suffered are also causing rancor among the kin.

Paris even took to her Twitter account to personally address Randy Jackson, essentially calling him a liar as she repeated his Twitter handle and charged: "Hello, dear family member. I don't appreciate you telling everyone things that aren't true, thank you very much." She's since deleted that tweet, but left up the followup that reads: "At this point I don't care what people call me or if they think I'm a bad person. If it means sticking up for my grandmother, I will do it."
