Antics: A new report by Us Weekly claims Scott Disick, 31, is in a dark place and is partying nonstop, pictured at Las Vegas' 1OAK nightclub, housed in the Mirage Hotel and Casino, on Saturday night

A source told the publication: 'Scott is in a very dark place. He's been partying nonstop.'

The claim comes just a little over a month after his son Reign was born on December 14, adding to his growing brood which includes Mason, five, and two year old Penelope.

Another insider went on to assert that Kourtney was 'sick' of Scott and 'his behaviour'.

And the tension is allegedly building with the same source claiming: 'Everyone on the outside says she has to leave him.'

Meanwhile, according to TMZ, the star had allegedly been staying at Hotel Jerome at the popular Colorado ski resort of Aspen when the management discovered their room was filled with empty bottles, cigarette butts and reportedly smelled like marijuana.

The hotel reportedly charged them $500 for the damage to go top of their reported $1,840 alcohol bill.

Scott – who had left Kourtney to look after their newborn baby Reign and two older children for the weekend – was joined by artist Alec Monolopy for the snowy break.

A hotel source claimed that one of the reality star’s friends stole a bottle of whiskey from the lobby bar and took it back to their room. Rather than contacting the authorities, the management instead charged $400 to their room.

According to TMZ, the drinking didn't stop there as they also requested another $840 worth of alcohol for the night, and another $600 the following evening.

MailOnline has contacted Scott Disick's representatives for comment.

Boozy weekend? Scott reportedly landed a hefty hotel bill after a drink-fueled weekend in Aspen with his pals

The father-of-three was meant to be on the straight and now after almost overdosing on sleeping pills last summer while filming Kourtney And Khloe Take The Hamptons.

Cameras rolled as Scott by his own admission ‘partied all night long’ and then took almost an entire bottle of sleeping pills.

The season finale of the series say Kourtney take aim at her own sister Khloe for being a bad influence on Scott while he tries to maintain his sobriety, but if the reports of a boozy weekend in Aspen is true it seems he's already jumped off the wagon.
