Joan Rivers and her daughter Melissa will trade living spaces and caregiver roles with Bristol Palin and her sister Willow on an upcoming episode of 'Celebrity Wife Swap.'
The E! network celebrities will head to Alaska to co-parent 4-year-old Tripp Palin while Bristol and Willow Palin take over the executive producing of 'Fashion Police' in Los Angeles, give a dinner party and care for Melissa Rivers' 12-year-old son, Cooper Endicott.
It seems likely that the mother-daughter duo will brush elbows with former governor Sarah Palin and her husband Todd while they temporarily reside in the commercial fishing mecca of Wasilla - population 7,831.
The Palin-Rivers swap will mark the season premiere of the ABC show. You can check it out Sunday, June 23 at 8 p.m.
