'He's on a mission to win her back': Scott Disick has 'cleaned up his act' in hopes to reunite with Kourtney 'for good'... amid rumours duo are living together again

They are rumoured to be spending Thanksgiving together amid reports they've moved back in together.

And it seems like a reconciliation between Kourtney Kardashian and Scott Disick - who split in July 2015 - is closer than ever with new reports claiming that the notorious party boy is changing his ways.

The duo are apparently living together with their three children Mason, six, Penelope, four and Reign, 23-months, at the $8.5 million Calabasas mansion they shared pre-split.

The news comes after Scott, 33, whisked the family away to Cabo, Mexico for a five-day trip. 

The entrepreneur 'spared no expense' for the trip, whisking his brood away by private jet. 

A source told the magazine that the duo resumed a casual physical relationship in January and then bonded over the summer.

Insiders say that Scott - whose hard-partying ways were partly to blame for the demise of the couple's relationship - has really cleaned up his act and that Kourtney, 37, 'is hopeful for a happy ending' after being encouraged by how much her ex is trying.

A Us Weekly source went so far as to say the mother-of-three wants another baby if things go well.

Scott is no longer interested in going on benders, sources tell the magazine, after his fourth and successful stint in rehab in November 2015.

The self-proclaimed 'Lord Disick' still drinks but has 'majorly cut back' according to one pal.

Meanwhile Kourtney has also asked Scott to do fewer club-hosting gigs.
