What are these two doing back together living under the same roof.
The pair who have three children together, Mason, Reign and Penelope where spotted leaving their a Calabasas home together, one day after Kourtney celebrated her 41st birthday.
This was the first time Kourtney has been spotted out and about for the first time in a month.
The pair tried to keep their presets under cover as photographers snapped away at them.
We wonder why they have been together?
