Scott Disick isn't planning on putting a ring on Kourtney Kardashian anytime soon, but for good reason.

"If it's not broke don't fix it," he said of his longtime relationship with his babies' mama. "We're happy the way it is. I don't even think we'll have time to get married at the rate that we're popping out kids."

The "Keeping Up With The Kardashians" star has three children with Kourtney. The children, he insinuated, have more of his focus, particularly newborn Reign.

"There's always so much in the beginning when they're that little and everyday is such a big milestone, but this is my third time so it's just kind of a charm," he told reporters. "You kind of know it by now. The first one was scary, the second one was less scary, and the third one you're like, I get it, I got a whole team over here."

Scott, however, might want to celebrate a different milestone. A personal milestone: He abstained from liquor while hosting a party at Las Vegas's 1 OAK. Sipping iced tea and water while his friends indulged in 50 Bleu vodka, Scott didn't even appear tempted to drink.

His sober evening stands in stark contrast to reports that he recently purchased more than $1,400 in booze in Aspen during a wild weekend. Who woulda guessed that Scott would visit Sin City and maintain sobriety!?
