Kourtney Kardashian & Scott Disick's Chateau Celebration

Celebrating the new year just minutes away from sister Kim, reality power couple Kourtney Kardashian and Scott Disick were busy tending to hosting duties at Chateau Nightclub and Gardens in Las Vegas on Saturday night (December 31).

The expectant momma and her man first snuck in a little gambling at a nearby casino's roulette table and a quick stop at the Sugar Factory before making their grand Chateau arrival.

Plunking down 100 bucks per entry into the bash, attendees enjoyed an open bar, midnight champagne toast and festive party favors throughout the night.

Adding to the night's star power, brothers Benji and Joel Madden provided the sounds for the evening on the hotel's rooftop - as the celebration had a scheduled end time of 5am!

Tweeting about the theater-going experience, Kourtney wrote, "Alvin and the Chipmunks!! Why did I want to burst out singing the whole movie?! Major dance party. Beyond cuteness!"

As for her baby on the way, Miss Kardashian's mom, Kris Jenner, recently spoke to Us about her preference as to whether her next grandchild is a boy or a girl.

Of her hopes, Kris said, "Half of me wants it to be two boys or two girls, [because] that's fun for a little playmate. And then, of course you want what they don't already have, but I am happy either way."

She added, "Whatever's meant to be will be. [I want] just a healthy, happy baby."

Held at Skylight SOHO, Jennifer Aniston and Demi Moore smiled while posing arm-in-arm while fellow contributor Alicia Keys brought her musician husband Swizz Beatz along for the blue carpet affair.

Set to debut on October 10th, "Five" is an anthology of five separate-yet-interconnected tales of lives affected by cancer - with Aniston, Moore and Keys among the five celebrity directors.

Of the project, Jennifer previously told Glamour magazine, "We were intrigued by the challenge of creating short stories that would defy audiences' expectation of the subject."

She added, "We wanted to balance the drama with humor and irreverence because that's what's helped our friends who've faced this get through their treatment."

Heading out for an afternoon venture, Kourtney Kardashian and Scott Disick were spotted leaving the Jeffrey Store in New York City on Monday (September 26).

Not one to jump at the chance to call a babysitter for their son Mason, Kourtney dished, “If it’s not a work thing -- if I'm going out to dinner with my friends, I don't have someone watch him. I don’t, like, go get a massage and have someone watch him. If I go to dinner he comes with me.”

The outing comes as Kourtney has been the subject of pregnancy rumors as of late, to which she responded via her blog by writing, "So there have been a lot of people saying lately that I have a baby bump because I have been wearing lots of flowy dresses or tops. I have definitely gained a few healthy pounds since I stopped nursing, but I don’t see a baby bump in these shorts!"

Miss Kardashian is also prepping her too-cute tot to tend to his ring bearer role at Kim and fiance Kris Humphries' nuptials, as she dished of getting Mason ready for his duties, “You know I was telling Kim that I think I am going to have a heart attack. I might be more nervous than Kim!”
