Having a new addition to the family has allegedly just made life even lonelier for Kourtney Kardashian, who has been forced to face up to the sad reality that Scott Disick would rather party than spend time at home with their children, according to a new report.

Instead of changing two-month-old Penelope's diapers, the wayward reality star has been hitting the town with a string of willing cohorts, including a group of flirty Canadian cocktail waitresses, according to one weekly magazine.

Disick, 29, reportedly met the fun-loving group while staying at the Westin Harbour Castle in Toronto on September 14 while he was in town to host an event at local hotspot Tryst night club, and even invited them to his hotel room to party until the early hours of the morning with his business partner.

The wild night was just the beginning of a weekend of debauchery that saw Scott passing around $500 bottles of Grey Goose vodka and knocking back beers at 9:30 a.m. in the morning at the Toronto airport before heading home, according to Life & Style magazine, while Kourtney struggled with sleepless nights feeding the baby and juggling mommy duties for two-year-old Mason.

According to the report, as the Keeping Up with the Kardashians star was up at dawn tending a screaming child, Daddy Disick had a crew of revelers back in his hotel room until 4:30 a.m. on September 15.

The couple are now reunited in Florida to film Kourtney and Kim Take Miami, but life in the Sunshine State is anything but rosy says the magazine, with the oldest Kardashian sibling worrying that Disick will disappear to South
