The temptations of Sin City proved too much for Kourtney Kardashian’s baby daddy.
But what happens in Vegas is unlikely to stay in Vegas when it’s taped for a reality show.
A tipple too many: Scott Disick visited Las Vegas in last night's episode of Keeping Up With The Kardashians and was tempted by all the drinks on offer
Guzzling it down: The father of one has battled alcohol problems in the past
The pair - parents to 19-month-old Mason– famously split over Scott’s drinking.
He had been sober for a year before the trip to Vegas to host a nightclub event – essentially getting paid to party with lashings of alcohol and beautiful women.
Kourtney had been understandably apprehensive before the trip but Scott reassured her he would be fine.
Lapping it up: Seen here lying by the pool with a vodka and lemonade, which he said would be his only drink of the day
Topping up the tan: The reality star was joined by his coercive friends who plied him with drink
'He’s been on such a good path I don't want anything to damage that.'
Scott even sought the advice of his therapist Erica Jaffe who told him to keep sober, warning that even one drink would be a slippery slope.
'I think for yourself having alcohol in you life is really dangerous for yourself and your family,' the therapist said.
But Disick argued: 'I needed to give up to get my life in order but I like to be able to feel normal and to have a drink maybe two drinks and fit in.'
Cracking open the champagne: One of Scott's pals emerges from the private jet they take to Vegas with bottles of champers in hand
Greeting him on the airstrip were pals with bottles of bubbly.
Kourtney said: 'All of his guy friends were there with bottles of champagne in front of me, it was definitely is not reassuring.'
Scott kept up the good intentions after arriving in Vegas – ordering just waters for his first round.
But soon enough a friend ordered one to many lemonade-vodkas and Scott couldn't help himself.
'Having this vodka and lemonade by the pool with me friends is pretty nice,' he said.
Worry: Back at home, Kourtney chatted to sister Khloe about her fears for Scott. She tried to call him repeatedly but he didn't pick up
After the first drink things quickly spiralled as he ordered a round of beers and more vodka-lemonades.
By dinner time Scott was hitting the hard stuff ordering Johnny Walker Black on the rocks – much to the concern of his boss ‘The Gooch’ who asked his if he was really drinking it.
Pretty soon Scott slapped Gooch in the face and in an awkward moment demanded another member of his group get up and do a song and dance for his entertainment.
Concerned: A glum-looking Kourtney drives Scott to the airport - but is not happy about him going away
When she tried to call him the phone went straight to answer phone arousing her suspicions.
At the club Scott continued to down drink after drink before making a surprisingly composed call to Kourtney from the bathroom where he insisted he was behaving.
He even made it back the following morning to LA without being caught out.
'I knew I would be fine and you didn't think I would be but it was easy,' he told Kourtney.
He added insult to injury by adding: 'I’m not going to lie to you – I think you owe me a pretty big apology!' The show returns next Sunday.
