But after Scott Disick was seen gallivanting with a seemingly never-ending of stream of younger models during their Costa Rica vacation, it seems Kourtney has finally turned their on/off strictly off.

The reality star, 37, hit the town with sister Kim, 36, her best friend Larsa Pippen, and bizarrely, Larsa's estranged husband, backetball star Scottie.

Loud and clear! After Scott Disick's recent gallavanting, t seems Kourtney Kardashian has finally turned their on/off strictly off if her necklace was anything to go by on Monday night

The foursome went out for dinner at The Nice Guy - and Kourtney made a statement with her necklace: a simple silver chain with the words 'off' attached.

This could be seen as a clear sign to the father of her three children, who reportedly fled Costa Rica after a ferocious row with Kim and her mum Kris Jenner after sneaking a woman into their hotel.

Kourtney looked unfazed as usual and showed off her jumper with cuts in the side alongside skinny spray on jeans. She rounded off the outfit with heels, and of course, that necklace.  

He's been partying and cuddling with two different women in Miami these last few days.

Despite his ongoing issues with partying and responsibility, Scott has insisted that he would never be able to move on from the love of his life.  

'I would never be over her,' Scott, 33, admitted in a new trailer for the upcoming episode of E!'s Keeping Up With The Kardashians. 'She's the love of my life.' 

As Scott professed his love for his ex and the mother of their three children over a voice over, the reality star could be seen affectionately rubbing Kourtney's arm.

Khloe Kardashian, meanwhile, was determined to get to the bottom of their ambiguous relationship. 

'Did you and Kourt, like, kiss?' Khloe asked teasingly. 

'We didn't kiss!' Scott quickly rebuffed as he blushes.
