The conversation occurred on Thursday night’s premiere episode of the last season of Keeping Up With The Kardashians. 

Scott revealed in that his close co-parenting relationship with Kourtney put strain on his relationship with his ex Sofia Richie whose father is Lionel Richie.

In fact he even claimed that Sofia gave him an ‘ultimatum’ demanding he choose either her or Kourtney with whom he co-parents their three children.

He made the bombshell allegation to Kourtney’s sisters Kim and Khloe Kardashian, saying he tried to balance his girlfriend with his children’s mother.

Although he attempted to have Sofia become ‘more of a priority’ he felt that she was ‘wanting to push Kourtney out’ of the equation, he alleged.

In a separate conversation Scott also sat down with Kourtney and was candid with her about the role their dynamic played in his split with Sofia.

‘When you first get with someone, everyone is like making changes and oh I will do anything because I’m so happy and so in love and so excited but then when it sinks in and it becomes real life it’s a lot different,’ Scott told Kourtney.

‘I don’t think I could do it the other way around but I’ve always been clear that my priority has been my children, my life with them and I even put it out there that taking care of you is one of my priorities.’

In a confessional he dished: ‘I realize that Sofia has been an absolute trooper but the truth is anybody dating somebody is going to feel neglected when their significant other is spending more time with their ex than with them.’
