The couple have remained close since announcing their split last October. A few weeks ago they were pictured holding hands in the airport on the way back from a family holiday in Thailand.
Then last week he took the Momager to hospital when she suffered stomach pains. Kris, 58, had a scan as a precaution and was then discharged, giving her the opportunity to spend Easter with her grandchildren.
Proving she was feeling much better, the reality star posted an Instagram photograph of an Easter table set up with treats for Mason and Penelope, who are the children of Kourtney Kardashian, and North, Kim Kardashian's baby with Kanye West.
She also organised a birthday cake, decorated with flowers and butterflies for Kourtney who turned 35 on 18 April. Her daughter celebrated with a holiday at a luxury beachfront resort in Mexico - before flying home to be spoilt by Kris.
And the festivities are not over for the Kardashian clan: Kim Kardashian and Kanye West are planning their wedding in France for this May.
