Scott Disick kept his relationship with Sofia Richie a secret out of ''respect'' to his former partner Kourtney Kardashian.

The 34-year-old reality star began dating the daughter of music legend Lionel Richie last year, and in Sunday's (11.02.18) episode of 'Keeping Up with the Kardashians' - which was filmed during the early days of their relationship - the hunk admitted he wanted to keep the blossoming romance quiet for the sake of his former girlfriend and mother of his three children.

In the episode, Scott - who has Mason, eight, Penelope, five, and Reign, three, with Kourtney - was being pressed on his romance with the 19-year-old beauty by Kourtney's mother Kris Jenner, and he later claimed he felt uncomfortable discussing his personal life with her.

He said: ''Kris really is like my mom to me, so I don't ever feel like she's putting me on the spot. But I don't really feel comfortable talking to her about my personal or dating life.

''For me, to see that Kris is invested in my life means the world to me. Because she's got so many other kids and so many other things going on, so the fact that she actually worries, loves and cares about me is probably one of the best feelings I have.

''Truthfully, as much as I'd like to be honest with her and tell her how I'm how I'm really feeling, I also do want to respect Kourtney and her feelings. Maybe down the line. but right now, my biggest thing is just being respectful of everybody.''

Elsewhere in the show, Kris spoke to her daughter Kim Kardashian West about Scott's new beau, but the 37-year-old star said she didn't ''care'' who Scott dated as long as he was moving on from Kourtney - who is now dating Younes Bendjima - and was ''happy''.

Kim said: ''Whatever makes him happy - I don't judge, I don't care. I think it's a good thing. I just hope that he's making good choices and having fun and that nothing is getting crazy.

''Scott has been so good in New York. I mean, it's not like we can keep tabs on him forever. He's got to live his life. Kourtney's moved on, Scott's eventually going to move on. If it ends up turning into something, great.''
