Kourtney Kardashian has managed to stay out of the headlines in the last several months, but that's mostly because her sisters Khloe Kardashian and Kylie Jenner have been dominating them. Yet, there's a new report that suggests we'll be hearing more from her as the reality television star's life is supposedly spiraling out of control, as she's been going on a partying binge that she just can't stop.

If it weren't enough that Kourtney has been dealing with her ex Scott Disick (who has been battling addiction problems of his own) and bad boy Justin Bieber, now sources say that the celebrity mom's behavior is also quite "troubling." She and Scott have three children together, Mason, Penelope and Reign.

On a recent trip to Las Vegas with her girlfriends, one insider told Naughty Gossip, "Kourtney was a complete mess ... She stayed out till 6 AM and barely made on the private jet home .... "

The report also goes on to call her a "hot mess." Although there are plenty of paparazzi photos that show Kourtney going in and out of Hollywood night clubs since her breakup with Scott, the brunette beauty has not made any comments about the most recent allegations.

Scott, for his part, has been making an effort to stay sober for the sake of the couple's three kids.
