Debi Mazar is ditching her Entourage to hang with Melissa & Joey.

TVLine has learned exclusively that the actress will guest star on the ABC Family fave as Harper Quinn, a straight-shooting political consultant/”spin doctor” enlisted by Mel (Melissa Joan Hart), who is seeking city council re-election. Harper enters the picture when Mel seeks her help in smoothing over a much-too-public scuffle.

Mazar’s episode is slated to air in spring 2012, when Season 2 of the comedy kicks off.
