After nine years together and three children, Kourtney, 36, ended her relationship with Scott in July after allegedly becoming tired of his excessive partying. It's been claimed the final straw were pictures of Scott partying with another woman in Monte Carlo.
In the new issue of Haute Living, her mother Kris said: "She's kind of my hero right now - she makes good decisions. She always puts her children first and is accepting, loving, and dedicated to her family- she doesn't get easily ruffled.
"This situation has made me realise how strong she is."
Kourtney and Scott have three young children together: Mason, five, Penelope, three, and son Reign, eight months.
While Kourtney has not publicly commented on the split, Scott did allude to it via Instagram, when he admitted the grass isn't always greener on the other side.
