The 36-year-old reality TV star dumped her troubled 32-year-old boyfriend of nine years, with whom she has three children, Mason, five, Penelope, three, and Reign, eight months, last month after he was spotted partying with an ex-girlfriend in the South of France, but Caitlyn insists she is ''doing as well as she can do under the circumstances.''
In a clip from an upcoming episode of 'I Am Cait,' the 65-year-old former Olympian, who was known as Bruce Jenner before undergoing gender transition in May, discusses Kourtney's emotional state with close friend Candis Cayne, saying: ''She's doing as well as she can do under the circumstances. It's obviously very tough on her. Obviously Scott has a lot of issues and she's trying to deal with them the best she can. She's got three kids with him...She will be O.K. Relationships aren't easy.''
Kourtney's mother Kris Jenner, who was married to Caitlyn for 22 years until late 2013, also recently praised her for putting her children first despite her heartbreak.
She said: ''She's kind of my hero right now - she makes good decisions.
''She always puts her children first - and doesn't get easily ruffled. This situation made me realise how strong she is.''
