Some temporary primetime changes are coming to CNN ahead of the premiere of “Piers Morgan Tonight” later this month.

For the next two weeks, Parker-Spitzer is going to get a second run at 11pmET and Anderson Cooper is going to be hosting at 9pmET until Morgan debuts Jan. 17. Cooper’s 9pm show has a talk format — bridging the Larry King-Piers Morgan gap, we suppose.

Tonight his guests include iconic women of comedy – Joan Rivers, Kathy Griffin, Joy Behar and Phyllis Diller. As we’ve been reporting, Cooper will be hosting his own talk show, syndicated on local stations across the country, beginning this fall. AC360 airs as normal at 10pm.
