Kris Jenner says Scott Disick is like a son to her.

The 'Keeping Up With The Kardashians' star will also be close to the 33-year-old television personality - who shares Mason, seven, Penelope, and Reign, two, with Kris' daughter Kourtney Kardashian - and admits he has had a ''challenging time'' of it.

She said: ''We knew Scott when he was 20 years old. He was a very young man, he was a baby! He was younger than Kendall is now for goodness sake.

''They started a relationship very young and had three beautiful children. His parents both died in the same year a few years ago. He's been through a lot ... I think he's had a bit of a challenging time. He's one of my kids, what can I say?''

And the 61-year-old television personality is hopeful her son Rob Kardashian's relationship with Blac Chyna will go the distance and believes it is a ''work in progress''.

Speaking about the couple - who are parents to two-month-old daughter Dream Renée - she added: ''You know, I think that, too, is a work in progress and they have good and bad days. It's a young relationship and they haven't known each other for that long.''

The momager also spoke about her daughter Kim Kardashian West, who was robbed at gunpoint in a terrifying incident last October.

Speaking on Australian radio show The Kyle and Jackie O Show, she shared: ''Kim has had a really hard time with the incident and the whole thing has been very grueling and draining.

''Apparently they did [catch the thieves]. I have not heard anything about it being recovered to be honest. I think we're just getting past people getting arrested.''
