Scott Disick has spent the last two days partying in Miami after he had a major bust-up with Kris Jenner and Kim Kardashian West.

The 33-year-old reality star abruptly left a family holiday in Costa Rica after Kris and Kim took issue with Scott for secretly flying another woman with him on their planned vacation.

A crew member working on 'Keeping Up with the Kardashians' informed the duo about Scott's behaviour and a fearsome argument ensued, according to TMZ.

Kris and Kim felt his actions were disrespectful - but Scott is reported to be much happier since he fled to Miami, where he was recently spotted being affectionate towards another woman.

Meanwhile, the argument is believed to have been completely unconnected to Kourtney Kardashian, whose on-off relationship with Scott has been the source of much speculation in recent times.

The duo - who share Mason, seven, Penelope, four, and two-year-old son Reign - split in 2016 after she became frustrated with his party-loving lifestyle.

And although recent rumours have suggested they could rekindle their turbulent romance, Kourtney is apparently happily single for the time being.

An insider explained: "Kourtney and Scott are not back together or even at the point of trying to make things work. Kourtney is happy being a parent right now and that is her number one interest right now.

"She's not interested in being in a relationship with anyone. [Kourtney and Scott] have a wonderful relationship and are doing an amazing job at being good friends for their kids. There is nothing more to it than that right now."

However, the brunette beauty is pleased Scott has managed to curb his drinking and regain control of his life over recent months.

The source said: "Scott is in a great place right now. He has toned down his partying and has done a really good job of staying in control. Everyone is really proud of Scott for sticking to his word and calming down."
